摘要
运用模态分析技术对CL250T摩托车车架的动态特性进行了试验模态分析,获得了车架振动模态参数和振型、固有频率及模态阻尼比,由此验证了车架结构设计的合理性。该试验方法可用于车架的结构分析中有限元模型的检验,是对摩托车复杂结构的试验分析的有利手段。
This paper gives a test modal analysis of CL250T motorcycle frame dynamic characteristic and obtain the vibration modal parameter andvibration model, inherent frequency and modal damp ratio. The result tests the rationality of motorcycle frame design. The test way can not only be used in verifying the FEM model of frame structure but also a favorable means to the test analyse of complex structure of motorcycle.
