| 摘 要： | 利用有限元理论以及大型通用有限元分析软件MSC.Nastran(前、后置处理软件采用MSC.Patran)对发动机支架进行了自由模态的有限元分析,得出该发动机支架的前十阶模态参数(固有频率和模态振型),计算结果对特种车辆采取减振降噪措施具有一定的参考价值。

| Abstract: | The finite element normal mode analysis for the engine bracket is made by using MSC. Nastran software ( pre-processing and post-processing software using MSC. Patran) on the basis of theory of FEA,and the first ten steps of mode parameters of bracket are drawn (natural frequencies and mode shaking types) , the calculation results has certain reference value to take measures to reduce vibration and noise in the special vehicle. |
