Through analyzed and optimized design for the structure of axle in the paper,based on the reason of rupture failure of aix,a suit of perfect research project of failure analysis and optimize of shafting parts is established based on the failure of axle.

• 通过对拐轴进行全面的结构分析及优化设计,以拐轴失效为原形和起点,提供一套较完善的轴零件的失效分析及优化设计研究方案。
