摘　　要：针对某型摩托车车架的振动问题,利用有限元技术,在摩托车整车基础上对车架进行振动响应优化设计。首先,在ANSYS/APDL环境下建立摩托车整车参数化优化数学模型,进行振动响应分析;然后对摩托车车架进行振动优化设计,得到各设计参数的优化序列;最后,通过修改设计参数,进行改进后车架振动分析。结果表明,参数的修改有效地降低了振动,实现了车架的振动优化设计。Based on a integrated motorcycle, for improving the vibration comfort the FEA is introduced to optimize the vibration response. First in ANSYS/APDL the integrated parameterized model is built. Then through the optimization design analysis the optimal design set is got. In the end a harmonic response analysis with the modification of some design variables is carried out. The analyze result shows that the vibration response of the frame has been reduced, and the frame has got to be optimal.
