Abstract: According to the production design specification, production recording materials in productive process and related test data, this paper analyzes the reason of power supply lug damage problem in impact test during the development process of the onboard secondary power supply. It explores the mechanism of the power supply lug damage in impact test, and puts forward the improvement measures of increasing the number of power supply lug. Then it verifies the improvement measures by theoretical analysis and experiment. The analysis results show that the measures improves the design margin of supply lug, and the test results show that the improvement measures are effective and significantly improve the design margin of power supply lug. The test results show that the test piece of power supply lug has no damage after the test, and increasing the number of power supply lug solves the problem of power supply lug damage in the impact test.

Keywords: power supply lug damage; impact; test
