ANSA was used to simplify the model and divided the mesh of two wheel pedal motorcycle frame・ The finite element model was built for the three loading conditions of front wheel horizontal, rear wheel vertical and passenger seat vertical in ABAQUS. The finite element analysis was carried out for the stress value and stress amplitude under the three working conditions・ The durability was checked according to the S-N curve, and the structural optimi­ zation scheme was proposed according to the analysis results, and make samples for test verification. The re­ search results show that the finite element analysis of motorcycle frame based on ABAQUS can effectively predi
