摘要

摘要: 以衔铁组件过盈联接压装过程为例，采用有限元分析软件ANSYS Workbench对其进行弹塑性分析，获得衔铁组件过盈联接的最大等效应力和最大压装力，并进一步研究了过盈量、摩擦系数和形状误差对衔铁组件过盈联接的最大压装力和最大等效应力的影响规律，从而确定过盈量的合理范围，进而确定压力-位移曲线的合理范围。随机抽取18套零件在已研制的压装设备进行压装实验。将有限元分析结果与实验结果进行对比，验证了有限元分析结果的可靠性，为衔铁组件过盈联接压装质量判断提供了一定的理论基础。

Abstract: Aiming at the interference suppression assembly process of armature component, the elasto-plastic analyses are performed with computer simulation software ANSYS Workbench. The maximum equivalent stress and maximum press-mounting force on the interference suppression assembly of armature component are obtained. The influence rules of the interference value, friction coefficient and form error on the maximum equivalent stress and maximum press-mounting force are further studied for the interference suppression assemblies of armature components, then the rational scopes of interference values of armature components, and then the rational scopes of interference suppression curves of armature components are determined. The 18 kinds of armature components selected randomly were assembled with the press-mounting device developed. Comparing the computer simulation results with the experimental, the feasibility of the computer simulation method was verified. The analyzing results provide a theoretical basis for the press-mounting quality judgment of the interference suppression assembly of armature component.
