摘　　要：利用ANSYS建立客车整车有限元模型,对整车模型进行了约束模态分析,在模态分析的基础上进行发动机激励的谐响应分析,考虑发动机垂向振动,研究发动机输出的简谐力引起的车身位移响应,以考察车身各部位的振动情况,最终提出解决客车振动的方案。The finite element model of the coach is established by ANSYS. The constraint modal analysis of the coach is carried out. Based on the modal analysis, harmonic response of engine incentive is analyzed and engine vertical vibration is considered. The vibration of various parts of the coach is studied through displacement response of the body caused by the harmonic power of engine. Finally the schemes of solving coach vibration are put forward.

关 键 词：有限元分析 模态分析 谐响应分析
