【Abstract】 In this paper, the UBET method is used to simulate the deformation process of bicycle flywheel casing, to optimize ring-shaped blank dimension. Some flow principles and process of ring-shaped metal are also discussed. The optimized blank dimensions are verified with experiment, and experimental results are identical with optimized results.更多还原
