摘要:
该文提出汽车八自由度振动系统力学模型 ,用前后四轮的路面随机激励作为系统输入 ,用广义拉格朗日方程和虚位移原理建立汽车振动系统数学模型。在2种路面和 2种车速工况下 ,对汽车平顺性及频率响应的模拟 ,其结果与实验吻合较好。该模型对载货货车的平顺性计算和动参数的优化设计有一定参考价值。
Abstract:
The 8-freedom dynamical model for the t ruck vibrat ion system is put forward. T aking the spect rum of road ex citation as the input of 4-w hell, a mathemat ical model was set up based on Lagrange equat ion and principle of virtual displacement. U nder the tw o different condit ions of both read surface and velocity , the t ruck riding smoothness w as simulated. The experimental results fit w ith the calculation ones. Therefore, this art icle is of certain value to the truck riding smoothness simulat ion and dynamical parameters optimizat ion desig n.
