本文主要研究如何开发汽车零部件台架耐久试验规范,通过n Code So Mat前端数据采集器测量采集整车六分力、底盘关键零部件应变、加速度等载荷数据,采用去温漂、毛刺、滤波、雨流分析、疲劳损伤计算等方法计算零部件的在道路试验过程中总损伤,通过等损失原理反推计算在台架上实现等疲劳损失模拟耐久试验时的加载幅值和循环次数。 This paper mainly studies how to develop the bench endurance test specification of automotive parts, and uses n Code So Mat front-end data acquisition to measure the load data such as the six components of the whole vehicle, the strain and acceleration of the key parts of the chassis, , Rain flow analysis, fatigue damage calculation and other methods to calculate the total damage of components during the road test. The load amplitude and the number of cycles during the simulated durability test of fatigue loss on the bench are calculated back by the principle of equal loss.
