In order to guarantee the durability performance of vehicle suspension component, the criterion for design and evaluation based on service loading condition are necessary. In this study, it was established durability evaluation criterion under Chinese service condition for SUV suspension system. The main parameters causing system failure were founded through the analysis of failure examples. The loading condition including the parameters was measured from the vehicle test on Chinese public road over 16,000㎞. The measured data was used to make the durability evaluation criterion by extrapolation method based on Chinese operating profile. To increase reliability of test, 1% severe driver conditions and risk factor was adapted into the test target. The 10-step block program test signal was designed to evaluate the durability of Chinese type SUV suspension system.
