摘要
论文主要对多自由度汽车结构振动模型进行分析与仿真,对于多自由度复杂的振动系统,目前较多采用较为复杂的拉格朗日的方法。该方法操作简单,但是计算量大,同时容易出现错误。因此论文引入有限元思想,利用矩阵的方法建立复杂的模型,通过Matlab/Simulink对该模型进行仿真,避免了对矩阵进行数值求解的困难,同时在该模型下得到的仿真结果对实际情况的更有参考价值。
This article mainly focuses on analysis and simulation of vehicle structure. For the complexity of vehicle vi- bration system, the prevailing method is lagrange. The process of this method owns property of simple, but its computation needs so much work and is vulnerable to errors. Therefore method of finite element is applied to set up stiffness matrix and damper matrix. To avoid the numerical computation of matrix equation, Matlab/Simulink is adopted. Then the results have more practice value.
