| 摘 要： | 结合LMSTWR软件,详细介绍了基于混合路面的轮心位移反求法求取副车架载荷谱的方法。通过在某MPV上布置合适传感器,在试验场测得道路载荷谱信号。根据实测的数据,建立整车多体动力学模型。基于处理后的道路载荷谱与多体动力学模型进行虚拟迭代,并进行副车架载荷分解。结果表明,迭代仿真得到的信号与试验值吻合度较好。

| Abstract: | Combined with the LMS TWR software,this paper,based on the procedure of spindle displacement back-calculation of mixed pavement,introduces the method of acquiring the sub-frame load spectrum.By arranging suitable sensors on an MPV,measure the road load spectrum signal.Based on the measured data,establish a multi-body dynamics model of the whole vehicle.Based on the above two factors,virtual iteration is applied to cascade sub-frame loads from the wheel hubs.The conclusion can be drawn that the signal obtained by iterative simulation agrees well with the experimental values. |
