摘　　要：为实现参数化分析．在AWE（ANSYS workbench environment）集成的（design modeler）环境中建立模型，并合理简化。在AWE集成开发环境下，设置自力型触头的工况对其进行接触压力分析，并对结果进行了理论计算校核。考虑到触指根部两侧小范围存在应力集中现象，利用DOE法（the design of experiments method）建立对应的参数化数值模拟，并对其小样本采集分析。根据计算结果确定其应力集中系数在1．20-1．27范围内变动。To realize parametric simulation, a model is set up with design modeler （DM） in ANDYS workbench environment （AWE）, and is reasonably simplified. The contact force on self-elastic contact is analyzed by setting operating conditions in AWE, and the results obtained are checked through theoretical calculation. Considering a small range of stress concentration at both sides of the finger root of a contact, DOE （design of experiments） method is adopted for parametric simulation, and small sample is acquired for analysis. Thus, the stress concentration factors is determined in the range of 1.20-1.27.
