基于六自由度轴耦合道路模拟试验机的悬架耐久试验研究

Research on Suspension Durability Test Based on 6-DOF Spindle Coupled Road Simulation Test Bench

本文基于六自由度轴耦合道路模拟试验机对悬架耐久试验的多种工况进行研究,重点分析了悬架在垂向回弹工况中无法直接进行垂向载荷迭代的原因,提出了将台架垂向位移作为目标信号进行迭代以实现模拟垂向回弹工况的方法。

Based on the 6-DOF spindle-coupled road simulation test bench, a variety of suspension durability test load cases were researched in this essay. The reasons why the suspension could not directly be iterated via the vertical load in the vertical rebound load case were analyzed, then a method was proposed that the vertical displacement of the bench can be used as the target signal to simulate the vertical rebound load case.
