本文提出了一个具有21个自由度的二系弹簧车辆分析模型,并利用势能驻值原理及形成矩阵的“对号入座”法则导引了其结构矩阵.通过计算与实测对比分析得到了本文提出的车辆分析模型对车桥振动分析是合理可行的结论.
In this paper, a 21-DOF spring-loaded two-wheeled vehicle model is proposed and its structure matrix is guided by the principle of potential energy and principle of “condemnation” forming a matrix.Compared with actual measurement, the proposed vehicle It is reasonable and feasible to analyze the vibration of the axle with the analysis model.
