什么是设计验证? What it mean Design Validation?
设计验证 Design Validation
设计验证是一个新车为了达到目标值,设计、开发和验证的过程,包括:功能、性能、可靠性和生产制造能力。 Design Validation is a process whereby the new car is designed, developed and validated for achieving Target, including function, performance, durability and production build ability
通过试制样车的制造(装配)、开发和试验完成的。 This is done through build, development and testing of prototype vehicles.
制造: 供应商和试制车间 Build : Suppliers & Prototype build shop
试验:试验开发部门(可靠性、主观评价、气候性试验) Testing : T&D dept ( Durability, Appraisal, Climatic test…)
开发:试验开发部门(NVH、操稳、白车身结构) Development : T&D dept ( NVH, R&H, BIW structure…)
装配、试验开发完成并实现目标值,然后图纸完结,最终大批量生产批准(工程完结) After Build, Test & Development completed and achieve Target, then Drawing will be signed-off, and finally approved for Mass production. ( Engineering Sign-off)

I’m very happy to have a discussion meeting with you today.
From now on, I’d like to Introduce the New vehicle test & Development process for Design validation.
*
OK, I’d like to discuss Mainly three topics about Test & Development.
Firstly the meaning of Design validation and Production validation.
Secondly, I will explain the Vehicle test & Development experience based on M11 car program.
And I’d like to explain CTTC’s Test & Development improvement activities.
Finally we can make a conclusion.
*
What it mean Design validation.
Many of Automotive company have their own definition,
but generally we can say,
“ Design Validation is……….”
“This is done through…….…”
"Build will be carried out by Suppliers and Prototype build shop.
Testing is done by Test group including Material test, Component test, Lab test, and Proving ground tests.
Development is done by NVH team, R&H team, Powertrain team, and others.
And After Build, Test & Development activities are completed successfully and all the Targets were achieved, Engineering sign-off will be made by Top management.
*
This chart shows the example of Prototype Development process.
PH1 might be a Body & Chassis structural test period,
and Crash tests, BIW tests, and Body & Chassis structural durability test should be carried out.
During PH2 stage, all of Checklist type tests and Development tests should be carried out.
OTS1 stage, PH1 tests to be repeated to confirm whether the all of Body and Chassis structural concerns issued from PH1 testing are solved or not.
OTS2 stage might be a refinement stage and all the Validation tests should be completed and finally Engineering sign-off to be done.
I think this process is very similar with Current Chery Car program development process.
*
Recently world leading Automotive company have different process.
Firstly Powertrain and Platform development are completed and then several kinds of Car models are developed.
It was well known that if we normalize the platform, total cost & timing required for New car development will be significantly reduced.
It is a good news that AERI already start to review this new concept and also Test team already start to review this process.
I think We need to improve Chery’s Engineering development process as soon as possible to improve our product quality and also to reduce resources and costs.
*
Production validation.
“The process whereby the……
“This is done through…..
“Supplier will have a responsibility for the Parts quality.
“And Manufacturing should improve the assembly quality.
And Function quality monitoring and Durability tests to be repeated again to confirm that the Pilot vehicles have same level of ESO targets.
*
This chart shows total New car program development process.
I think Design Validation should be completed at P5,
And Production validation should be completed P8, before SOP.
In case of our quality gate, these sign-off requirements should be defined more in detail.
*
Secondly, I’d like to explain M11 Test and development experience.
*
When M11 test team review the M11 styling model, M11 team started to discuss How to tune this Nice looking, mid size family car.
*
Program manager give us the general target, Comfortable drive, Best in class fuel economy and at least 4 star Crash target.
And CTTC vehicle development team to consider the vehicle function target.
“Balanced R&H
“P&E optimization
“Comfortable interior environment,
“Acceptable NVH level, smooth sound quality,
“ High quality of durability.
*
We run many of benchmarking tests and finally we decided the engineering targets.
*
During Prototype test period, M11 test team had carried out Test & Development work for Design improvement based on the test plan.
Through M11 development, many engineers were trained and we can improve out test capabilities, too.
*
And also Test team and Design team, PM team had lots of discussion, How to improve the Team work, how to solve the problems,
and finally we can improve many kinds of T&D Process.
Now we still try to improve, so called CCPMS, “CTTC Car Program Management System” internally.
*
Finally we complete the M11 development work successfully.
I heard that A3 is now very popular in the market.
*
OK, From now on, I’d like to explain more details about the Test and development activities for Design validation.
Firstly T&D Program management.
*
As I explained just before, CTTC is trying to improve the New car Test & Development process to contribute more on Design validation work.
CTTC’s process should be integrated with Chery R&D process, and CTTC’s T&D Process should be agreed by Program managers.
And CTTC internally, we are trying to build strong car program team to give more effort to improve the Performance or to carry out the problems solving work more closely with design team.
*
This shows current Chery quality gate system.
From last year, CTTC try to understand Chery quality gate system
And based on this system CTTC try to establish more detail Test & Development process.
And we found there were lots of items to be improved regarding Responsibility, Targets, milestones, etc.
*
This chart shows example of new car program scale ability.
If Program team release the VTS for the new car development, CTTC Test engineer will define what are the new parts, What kinds of tests are required.
*
After reviewing the VTS, we define T&D work scope.
CTTC Vehicle test team have a capability to run 220 vehicle test items including Baseline test, Development test, Validation and also homologation test.
After reviewing VTS, and depends on Target level, T&D procedures for development, for Validation will be decided and to be proposed to program team and Designer.
*
For example, If we have New engine application program to Current platform without Upper body change,
Test & Development items to be as follows:
Vehicle performance & Economy improvement test
Engine related NVH Development tests
Transmission driveability improvement
HVAC & Cooling tests and Heat damage tests should be run.
R&H, Brake evaluation just for confirmation
Engine durability
And General durability for Validation can be carried out.
*
Depends on Car program scale, for example, Major car program, minor car program or just face lift program,
we can judge the development lead time, Test procedures, No. of prototypes needed and Test budget.
*
Finally T&D Timing plan to be proposed to Program team.
In this T&D Plan,, I assume total 40 months From feasibility study to SOP if under floor, upper body are new and Powertrain is carried over.
If New engine is installed on new car program, maybe total development period will be more than 40 months.
If just modified platform to be used, total development timing might be shortened.
Based on this T&D Plan, CTTC T&D Mangement work will be carried out.
*
Now I’d like to introduce another example, R&H development process.
*
If new car program is proposed by Program management team,
Chassis designer, CAE engineer and R&H engineer should make a CHASSIS DEVELOPMENT PLAN.
This team will define the character of new car through Competitor analysis and market analysis,
Then carry out benchmarking test and finally target to be proposed to Program manager.
Maybe we can call this stage “ Concept development stage”
Also this stage, Concept drawing might be released and initial CAE work to be started.
*
In case of R&H character, Once CTTC proposed 5 types of Characteristics.
Base model is Balanced R&H
Level 1 is more ride comfort car
Level 2 is Handling, or fun to drive car,
Level 3 is Sporty car
Level 4 is Luxury car
In terms of Handling, Comfort and steering, we can choose the character based on Styling, Engine power, Vehicle cost, Susp design, etc.
*
During Production development stage, R&H Development work through mule car testing, iterative Prototype tuning tests to be carried out,
and all R&H Development work to be completed at the P5 point
Then engineering sign-off to be made by Program manager.
*
Based on the Vehicle development process, Our R&H team produced Detail R&H Development process including
Planning, Milestone & Responsibility, Procedures and Data analysis process.
This sheet shows Timing plan for R&H development.
This sheet define R&H related activities from P0 to P9, and shows Deliverables at each quality gate.
This shows What test should be done at each stage, Benchmarking, Mule car, Prototype and Pilot stage.
This is test items for Target setting.
This is so called Target book. All of benchmarking data to be recorded in this sheet.
This shows prototype vehicle & Component build requirements.
This is Tuning parts list.
In case of R&H test data, All the data to be recorded during whole New car development period based on this format.
Level 1 Subjective evaluation results.
Level2, Objective data.
Level3, K&C data,
I hope we can improve more after discussion with CAE and Chassis design engineer together
and then this new process can be implemented to new car program.
*
Next, I’d like to explain Durability program.
*
Normally durability test require long period of timing and Test costs are pretty high.
It means we should have very accurate Durability test procedures for System and/or Vehicle validation.
Most of Automotive engineering center have similar durability test procedures.
Accelerated Body & Chassis structural durability test
General durability for whole vehicle validation
Engine durability test program
Corrosion test,
Fleet test, etc.
*
And normally all kinds of durability test procedures are correlated to 160,000Km Customer driving mileages.
*
Recently Durability test can not be done by Vehicle on-road test due to reduced program timing.
So we should consider so called Integrated durability test program.
It means, CAE FATIGUE ANALYSIS, Rig and Bench test in the Lab, Proving ground test should be correlated each other.
Component, System and Vehicle Durability development should be done through CAE Analysis and Rig test in advance,
and finally whole Vehicle durability test should be carried out for final design validation.
*
This shows Correlation between Customer’s driving environment,
Component, Module or Vehicle system lab test and Proving ground test.
*
This chart shows Durability test program operation concept.
CTTC durability team are now considering 3 iteration durability test operation.
Iteration 1 will be problems finding and Design improvement stage
Iteration 2 will be design validation stage
And Iteration 3 will be a production quality validation stage.
*
This chart shows Durability plan for the new Car program.
Depends of the New car program scale, We can define what test should be carried out and How many iteration to be required,
Then Durability test timing plan, No. of test vehicle will be decided.
*
It shows Durability Target at P5, and before SOP timing.
Recently, Chery durability committee had started to discuss how to improve durability quality of Chery Product.
And CTTC durability test team is going to propose the Durability target.
Before SOP, all Critical items should be closed.
Maybe there must be lots of discussions how to achieve this target.
*
OK, Now I will explain about the Closed loop system and Engineering sign-off
*
This chart shows Problems solving process.
Principle is very simple.
If problems or Concerns are issued through testing, Concerns will be reported to related Designers,
And all the concerns should be discussed with related Engineers
and Improvement plan should be decided
Then re-test should be carried out for confirmation.
After re-test, and if meet target, open items will be closed.
*
This chart shows the process how to close the concerns issued from Durability test.
If test engineer find out the problem, this problems will be reported to related engineers and listed up on the CR summary,
And through Design review meeting, Test engineer and Designer should make improvement plan.
R1 date should be proposed by Designer, R2 and R3 date should be proposed by Durability test engineer.
And if improved sample is available, Same test should be repeated to confirm the problems is solved or not.
If problems occurred again, then 2nd design improvement to be carried out.
*
I think durability quality of our product is not good and many of our customers are complain about this.
How to improve the Quality ?
If designers provide high quality prototype drawing,
and if Supplier to provide good quality prototype parts based on Prototype drawing,
And if Prototype build quality is improved more from the early prototype stage,
Then CTTC can start durability test from the early prototype stage,
It means CTTC can find out the concerns more early,
and Designers can have enough time to improve the drawing,
And if CTTC run confirmation tests exactly, then our product quality should be improved.
*
Actually Closed loop system is very complicated for engineering sign-off.
Early stage we establish the engineering target. Then We establish the test & Development plan.
Many kinds of test and development work should be carried out through Material, Component and Vehicle testing.
And all the test results and Improvement activities should be documented through reporting system,
At P5 point, All the test should be completed and all target should be met.
And finally Engineering sign-off will be made by top management.
*
OK, Conclusion
*
CTTC is now trying to establish the New car program Test & Development process based on Three principles.
First one is Team work.
*
This figure shows the relation ship of Vehicle attribute and vehicle system.
We can say all of vehicle attribute are integrated with every system of the vehicle.
It means Designers, CAE engineers and test engineers should understand each other to achieve balanced Target for the WHOLE vehicle attribute.
Team play, communication, sharing the technology and information, these kinds of things are very important for Vehicle development.
*
Second one is Technical capability improvement.
*
Most of working level engineers in Chery are very young
and we need to improve their engineering capability as quickly as possible through training.
An also we need to improve process management system simultaneously.
And both Function technology and Process management should be combined together, then we can produce High quality Low cost car to our customers.
*
Third, Target ownership
*
Before we start the new car program, related engineers should define the New car’s character and engineering target.
The target should meet both customer desire and Chery brand values.
Based on the fixed target, all of related engineers and team should try their best to achieve the target.
After we achieve the Design quality target, Parts quality target and assembly quality target, then our new vehicle can be introduced to market.
We should continuously investigate any field claims or Customer complaints,
and we can improve more and more for Customer satisfaction.
*
I think Test & Development work is one of important task to improve Vehicle quality, like CAE, DESIGN, Prototype build, Quality Control, etc.
Currently CTTC is trying to establish the new improved T&D process including T&D Planning, Test technology, Development capability and analysis capability.
I hope this CTTC’s T&D activities will contribute more to improve Product quality and also do more contribute to your design validation work.
