Abstract: With the continuous acceleration of the vehicle development process, the importance of the test track accelerated durability test method in the vehicle project development process is increasingly prominent. Based on the road load spectra collected from multiple vehicle model projects, this article successfully transplanted the durability test specification of an external professional test track to the company's internal test track by conducting damage calculation and analysis on the vehicle and key components. According to the principle of damage equivalence, while ensuring the certification quality, it significantly shortened the test cycle and reduced the test cost, and at the same time improved the response speed of problem solving, enabling the rapid and accurate test certification of the vehicle chassis structural components.

Key words: test track; structural durability; specification transplantation; damage equivalence
