Abstract
The load spectrum of a frame, which is a key component of a motorcycle, can be used to frame loading experiment and life prediction of a motorcycle. Through the dynamic characteristics analysis of the motorcycle frame, we can get the dynamic model of the weak parts in line with the actual conditions, as well as the preparation of the load course make it to become the program load spectrum for experimental load. Taking a 125-type motorcycle for example, establish the finite element model of the frame for modal analysis and transient analysis. Establish the fatigue load spectrum of the hazardous locations by analysis. Provide a realistic experimental methodology of program load spectrum.
