摘要

根据对载荷实际作用效果的认识,确定了危险测点信号的无效载荷区间,编制了多级程序载荷谱。明确了造成后桥失效的主要关联载荷,对台架试验加载方式进行了简化。在此基础上,完成了扭转梁后桥快速加载试验,结果显示:台架试验失效部位与道路试验一致,能够实现耐久性快速评价,加速系数为5.68。

Abstract

According to the understanding of the actual load effect on the rear axle,the invalid load interval of critical modulated signal can be decided to compile the multi-level program spectrum. The loading mode of bench test is simplified on the basis of recognization of the failure correlated load on the rear axle. Accordingly,the durability test of torsion beam rear axle is completed from the work above. The results show that the failure region of bench test is coincident with road test which can reach the accelerated assessment of durability,the acceleration factor is 5. 68.
