摘　　要：为有效解决摩托车的振动问题,论文对车架结构动态性能进行了分析,建立了车架结构优化的数学模型。基于车架的有限元模型,进行了动力学灵敏度分析和优化设计。通过改变车架的板厚、管径、壁厚等,在满足约束条件的前提下,达到了性能匹配效果,有效的降低了振动。In order to effectively reduce the vibration of motorcycle, the dynamic performance of motorcycle frame is analyzed and the mathematic model for structural optimization is established, Based on the finite element model of the motorcycle frame, the dynamic sensitivity and optimization design are investigated, and the structural parameters are optimized, such as the thickness of motorcycle frame＇s plates and tubes and the diameter of the pipe. The results show the optimization structural parameters can meet the needs of the constraints and can get better matching performance. Thus the vibration of motorcycle can be reduced remarkably.
