Motorcycle frame structure based on finite element modeling of static strength analysis and improved design

The research and application of finite element analysis software to establish the motorcycle frame finite element model,the structural static strength analysis,modal analysis,improvement of before and after comparison and stress test,puts forward the frame structure optimization improvement scheme.Analysis results show that,the improved frame whole stress value decreased,upper beam tube and the reinforcing plate joints stress concentration phenomenon can be improved greatly,the overall deformation of frame than the unimproved decreases,has a good damping effect,better comfort.According to the motorcycle frame finite element analysis of key components and structure optimization for motorcycle design and development,laying a solid foundation for random dynamic simulation,motorcycle overall design will be relying on this basis,the application of computer aided industrial design3D data model establishment,validation and modification,can greatly reduce the work flow,improve the work efficiency and the integrated level.
