摘　　要：利用UG NX8.0软件对摩托车挡泥板进行有限元建模和动力学响应分析。通过对挡泥板有限元模型的模态分析,求得固有频率和几何振型。求解了在同一路况不同速度对前挡泥板结构的影响,探讨了影响摩托车挡泥板振动的几个因素。并与模态分析结果做了对比分析。这对于摩托车挡泥板结构的设计和破坏原因的预测等,都具有一定的指导意义。In this paper, the finite element modeling and dynamic response were analysed using NX 8.0, and found its natural fre- quencies and mode shapes. On the basis of the fender structure modeling on different road with the same speed, this paper inves- tigated the factors that the vibration motorcycle and analyzed true fender of the motorcycle and did comparative analysis with the modal analysis results. It is helpful to the design of the fender structure and the estimation of the fender fracture.
