乘用车悬架总成道路模拟试验迭代方法研究

Research on Iterative Method of Road Simulate for Car Suspension Assembly

应用轴耦合整车道路模拟系统,结合某车型多连杆结构后悬架总成,采用固定载荷反应约束方式,对不同模拟迭代方法进行研究。结果表明,采用轴头六分力及控制臂应变信号作为期望响应的方法能够很好再现悬架部件与道路相同的载荷激励,对于仅有车轮六分力而缺少悬架其他部件载荷的道路模拟试验,将轴头加速度信号参与迭代可以提高试验结果的准确性。

Applicated spindle coupled vehicle road simulation system,combined with the multi-link suspension assembly of a vehicle structure,using different ways of iterative method to implement fixed-reacted road simulation test,the results show that the iterative method of jointing six-axis load and strain signal of control arm as the expected response can well reproduce the same load path.
