摘要
针对某款125摩托车手把振动剧烈的问题,在LMS.TPA分析软件中分别建立了2个不同的振动传递路径分析模型,并获取传递路径计算模型所需的频率响应函数,将2个不同模型的振动贡献总量与直接测得的贡献总量进行对比,选出了能够反映实际振动的模型,分析每条路径的直接贡献量,最终得出结论:车尾部摇架上的传递路径是手把振动的主要传递路径。
To resolve the severe vibration problem of a section 125 motorcycle handle,two different vibration transfer path analysis models are established by using LMS.TPA analysis software and the Frequency Response Functions necessary for transfer path calculation models are obtained.The model that could reflect the actual vibration is selected by comparing the total vibration contribution of each model with the total vibration contribution directly measured respectively,and then the direct contribution of each path is analyzed.Finally,it is found that the transfer path of the rear shelf is the main transmission path of hand vibration.
