利用有限元法，建立某厂螺杆钻具传动轴的力学模型，从静力学及疲劳两个方面对其性能进行分析。并通过ANSYS Workbench软件分析确定传动轴可能存在危险点的Von Mises应力值。从生产实际出发，提出了两种改进的方案。利用局部应变法中修正后的史密斯公式对传动轴进行寿命预测，为传动轴的设计提供了理论依据。

In the paper,the mechanical model of drive shaft is established by finite element method, which is analyzed from two aspects of static and fatigue.Through the ANSYS software, the dangerous point of von Mises stress value is defined.Two improved schemes are presented by actual production.Using the revised Smith formula of local strain method to predict the fa-tigue life and a theoretical basis is provided for the design of transmission shaft.
