【Abstract】 To improve the market competitiveness and performance of motorcycle, The structural fatigue life of a bestriding motorcycle is analyzed. Tthe motorcycle structure is appropriately simplified to build the finite element model. On the basis of the finite element model, structural fatigue life is analyzed under the excitation of dynamic loading gathered from the test track, and the analysis result is according to the test one. The analysis is referential to improve the motorcycle structure.更多还原
