School of Mechanical and Precision Instrument Engineering, Xi'an University of Technology, Xi'an 710048, China

摘要

摘要: 结合冷滚打成形工艺的特点，基于Python语言对有限元分析软件ABAQUS进行二次开发，建立了冷滚打成形有限元模型的参数化建模插件，利用该插件可以对滚打轮和工件的几何模型、复杂材料属性以及打入深度、公转速度、进给速度等工艺参数进行便捷更改，实现冷滚打有限元仿真模型的参数化建立，自动完成几何建模、网格划分、材料属性定义到提交作业等一系列前处理过程，最后使用该插件进行了仿真模拟，并进行了冷滚打试验研究，对不同转速下的仿真成形力和齿形轮廓与试验进行了对比分析。结果显示：仿真所得成形力和齿形轮廓与试验都有相同的变化趋势，并且误差都控制在6%以内，验证了利用该插件建立冷滚打有限元模型的可行性和有效性。

Abstract: The finite element analysis software ABAQUS was developed based on Python, by combining with the characteristics of cold roll-beating forming, the parametric modeling plug-in of finite element model for cold roll-beating formingwas established. The plug-in can be used to easily change the geometric model for rolling wheel and workpiece, complex material property, rolling depth, revolution speed and feed speed and other process parameters of parametric modeling, and realize the parameterization of the finite element simulation modelfor cold roll-beating forming, so as to automatically complete the geometric modeling, mesh, material property definition to submit a series of pre-processing process. Finally, the plug-in was used in finite element simulation, and the experiment of cold roll-beating forming is carried out. Through the comparative analysis of the simulated force, tooth profile and experiments under different parameters, the results show that the simulated force and tooth profile have the same variation with the experimental results, and the errors are below 6%, the feasibility and effectiveness of the plug-in used to establish the finite element model for cold roll-beating formingwere verified.
