What does the DVP trial program mean?

The meaning of the DVP program is:

Design Verification Plan and Report (DVP&R).

Design Verification Plan and Report (DVP&R) is a method for planning and documenting pilot activities throughout the product process development from inception to each improvement phase. This method was used by Chrysler and Ford.

Effective dvp&r provides accurate working documentation to help Engineering Valley in the following areas:

By requiring the responsible party to ensure that the component or system meets all engineering requirements, a comprehensive and complete plan is drawn up in order to arrange a reasonable sequence of tests;

The goal of ensuring product reliability to meet customer requirements;

Pay attention to the customer's request to accelerate the pilot program in terms of schedule;

Provide a working tool for the relevant responsible departments:

Summarize the functional, durability and reliability test requirements and compile them into a single document for easy reference;

Provides the ability to easily prepare test status and progress reports for design reviews.

DVP stands for Design Verification Plan. Refers to a verification plan for a newly designed part.

In layman's terms, it is a pilot plan. These include bench tests and vehicle tests. The purpose is to ensure that the design parts meet the functional requirements and meet the design requirements in the future use process.

The test is divided into DV and PV, DV is DesignVerification design verification, and it can be manual parts or mold parts at this time. PV is ProductVerification product dry bench verification, which must be mold parts, and produce only the parts made on the production line from the first supplier. After PV, the parts after the PPAP audit are completed, and they are qualified for mass production and supply.

DVP Test Requirements:

The test requirements are generally decomposed by decomposing the requirements of the product, which are common to the whole vehicle and components, and the requirements here include the expectations of the market and the laws and regulations of the country.

the needs of the users and so on.

In terms of vehicles, China has mandatory inspection standards for passenger cars, about more than 40 items, for vehicles that can be sold in the market, these tests must be passed, everyone can also go, not to say more here. Individual manufacturers will also make some other requirements for the product, such as noise, vibration, etc., so these experiments are inevitable.

Trials are also divided into developmental trials and batch approved trials according to the different stages of the project, and the two may overlap, but they are not exactly the same, and the purpose is also different.

The above content refers to Encyclopedia-DVP

DV (Design-Verification) Testing is a design verification test: the purpose is to verify whether the product design meets the specified requirements. DV testing is the physical testing of pre-produced or produced parts.

PV (Production-Validation) Testing is a production validation test: the purpose is to verify that the product is produced using mass production processes and tooling to meet the requirements. The PV test is a physical test of the first piece of mass production.

After the main engine factory and the first-class business jointly formulate the DVP (or PVP), the more important work of reading the silver number is to strictly implement the content, requirements and time in the test plan; If there is a problem in the test, a series of corrective measures need to be proposed to achieve the goals of the system and the whole vehicle. Different parts, especially live parts, may involve more items (more functional requirements).

However, whether it is a DV or PV test, the formulation of the test plan will involve many departments, especially the design and development department, the test department, as well as the vehicle performance department and the quality department, etc., all of which need to be involved in the entire test process.

The design and development department is responsible for the release of DV test plans, test capability analysis, organization of DV tests and test process control, and leading the organization of verification and review of DV tests. The performance department takes the lead in rectifying the quality problems of DV test design defects, assists the test department in the release of DV test plans and the development and tracking of DV tests, participates in the verification and review of DV tests, and conducts business capability inspections.

PV mainly includes:

1. Test item no, such as, etc.

2. The test standard procedure or standard based on the test, such as ES000232-05 section.

3. Test description.

4. Test method.

5. Acceptance criteria for the test.

6. The reliability of the test requires target requirement, such as 100% pass, R90C90, etc.

7. Test responsibility.

8. Test stage, such as DV, PV, EV, etc.

9. Test quantity and type.

10. Actual test result.

11. Note, this item usually stipulates the precautions and special requirements of the experiment in detail.

The DVP test of parts and components is the product verification plan, which is to verify whether the product meets the design requirements by conducting reliability tests, durability tests and other related tests after the initial sample is manufactured.

DVP&r This test document is a guidance document for product engineers to carry out targeted testing according to the product technical specifications provided by customers, referring to previous product design experience and lessons, in order to verify whether the product design can meet customer requirements and design requirements.

Its main purpose is to purposefully evaluate the quality of the design through experimental means after the completion of product design. Since DVP&R is developed on the basis of the technical specifications provided by the customer, when it is found that the DVP&R is inconsistent with the technical specifications provided by the customer, the DVP&R shall prevail.
