【摘要】 <正>焊接强度问题是离合器齿毂总成设计的一个重要问题。为了确保离合器齿毂总成的安全,需要分析离合器齿毂和离合器内架的焊接强度,因而利用有限元理论和台架试验进行研究。首先根据现有的离合器齿毂总成,建立了其CAD模型。在对几何模型化简、网格划分的基础上,参考企业和试更多还原

【Abstract】 Weld strength is an important part in designing clutch hub assembly.In order to guarantee clutch hub assembly reliability,weld strength is analyzed and researched with FEA theory and bench test.Firstly, CAD model is built based on the existing parts.After the model is simplified,the girding is meshed, boundary conditions are handled,and FEA model is established to analyze weld strength of clutch hub assembly according to the company standard and test requirements document.And then the result of FEA is obtained.During weld strength test of clutch hub assembly,three test pieces are chosen.Bench test of it is finished with principle of work.The failure mode of all test pieces happens at welding line between clutch hub and inner tower.The weld strength typical value of all test pieces is 227.943KN.After the results of FEA and bench test are studied,the conclusion can be reached that simulation curves are similar to test curves.Yield stress appears about 155KN in me simulation curve,while Yield stress appears about 150-160KN in the test curve.Based on analysis and discussion,the relation curve of load and displacement has a better linear relation in the elastic deformation.Finally the clutch hub supplies the demand of design.更多还原
