중국 RLDA 데이터에 의한 조향계 내구 시험모드 개발

In order to guarantee the durability performance of vehicle steering component, the criterion for design and evaluation based on service loading condition are necessary. The criterion should describe service loading condition because it has much diverse range due to different driving area and culture. In this study, it was established durability evaluation criterion under Chinese service condition for Chinese type steering system. The loading condition including the parameters was measured from the vehicle test on Chinese public road over 8,600㎞. The measured data was used to make the durability evaluation criterion by extrapolation method based on Chinese operating profile. The block program test signal was designed to evaluate the durability of Chinese type steering system.
