Abstract

The invention provides a service life verification method of an automobile part product, and belongs to the technical field of service life verification of automobile part products. The method comprises the following steps that: (1) a reliability test is carried out on an automobile part product according to a standard specification, wherein the reliability test comprises all test items specified in the standard; and (2) if the tested product passes through all the corresponding test items, it is judged that the tested product can reach the designed service life, wherein the designed service life is obtained through calculation according to the mileage in the performance corresponding to the reliability test or obtained according to the useful life in the performance corresponding to the reliability test. The service life verification method for verifying the service life of an automobile part product according to a reliability test result is provided, the service life of the product does not need to be verified through independent accelerated service life test, the test time can be saved, and the test efficiency is improved; and the service life verification benchmark of the same kind of automobile part products is unified, and the service life verification result is accurate.

Description

technical field [0001] The invention relates to a life verification method of auto parts products, and belongs to the technical field of life verification of auto parts products. Background technique [0002] Lifespan is an essential indicator for product design of auto parts and a key basis for whether a product is competitive. How to determine whether the life of auto parts meets the design requirements, and how to evaluate whether the auto parts meet the design requirements in the shortest time are the difficulties in the current industry. [0003] At present, two kinds of tests are required before leaving the factory for auto parts products. One is reliability testing, which is used to verify whether the reliability of the product meets the design requirements; the other is life testing, which is used to verify whether the product life meets the design requirements (that is, whether can reach the design life); the current life test is divided into two types, the first i...
