Statics and Vibration Analysis of Motorcycle Frame based on Finite Element Method

采用系统动力学分析技术与有限元分析技术的基本理论和方法,以摩托车车架为研究对象,对车架结构做了静态的应力和应变分析,用动载系数法做了动态的应力和应变分析.指出了车架结构的薄弱环节,说明改进途径.结果表明,应用Hyperworks软件可以较准确地分析摩托车车架上各点的应力、位移情况,为改进摩托车车架受力状况和结构优化设计提供理论依据.

The technology of finite element method （FEM） and system dynamics analysis were used for the design of the motorcycle frame. The static and dynamic stresses and deformations were analyzed. The weak structure of motorcycle frame was pointed out and the improving methods were offered. The result showed that the accurate analysis on every point＇s stress and deformation of motorcycle frame can be obtained based on the software of Hyperworks, which can offer theory foundation for the improvement of the stress of motorcycle frame and the optimized design of structure.
