英文摘要：

In order to minimize the weight of three-wheeled motorcycle frame and optimize the frame structure,finite element theory is applied to analyze frame stress and strain through load simulation of frame under different conditions. Design explorer modules are employed to obtain the frame lightweight design scheme by lightweight design of structural parameters. This method could optimize the three-wheeled motorcycle frame and provide theoretical basis for improvement of the frame and lightweight design.
