摘要/Abstract

摘要： 以某款摩托车车架为研究对象,在试验场强化路面上采集载荷谱,并对原始数据进行滤波和压缩等处理。基于实测载荷谱,利用摩托车两通道道路模拟试验台,以实测载荷谱为初始输入进行等效迭代,得到近似实际路面的激励谱。利用 CATIA三维建模软件和ADAMS多体动力学仿真软件,建立某摩托车车架刚柔耦合虚拟试验平台;以提取的激励谱为输入进行仿真分析,并结合道路模拟试验结果进行仿真结果验证,从而建立了基于实测载荷谱的摩托车车架虚拟振动试验方法,为摩托车车架结构设计改进和性能考核与评估提供了一种行之有效的手段和方法。

Abstract: Taking a motorcycle frame as an object,the collection of practical road load spectrum in the proving ground and the treatment of equivalent damage are introduced to compress test cycle significantly.Using the motorcycle road simulator of two channel test stand,taking the load spectrum for initial input,the closed real road excitation equivalent input signal is obtained by iteration.By using the CATIA software and multi-body dynamics simulation software ADAMS,the virtual rigid-flexible coupled road simulation test platform is built with reference to the actual motorcycle frame road simulation test bench.Simulation analysis is conducted with the achieved road simulation excitation spectrum as input and the outcomes are verified by road simulation test results,thus the virtual vibration test method for motorcycle frame based on measured load spectrum is established,an effective methods for motorcycle frame structure design and performance assessment is provided.

Key words: motorcycle frame, load spectra, road simulation, virtual test
