万向联轴器叉头断裂区域优化研究
|
摘要
针对万向联轴器中叉头断裂的问题,以SWC-225CH型万向联轴器叉头为研究对象,利用HyperMesh软件进行力学分析,得到其最大应力所在区域与实际断裂位置吻合。利用OptiStruct软件对叉头进行拓扑优化,最大应力从260.3MPa下降到213.8MPa,断裂区域结构外形向外增加1.62mm。结果表明:优化后叉头断裂区域应力远小于其材料的许用应力,并提高机械结构强度。
In order to solve the problem of fork-head fracture in the universal coupling,the SWC-225 CH universal coupling fork-head was studied,and the mechanical analysis was carried out using HyperMesh software to obtain so that the maximum of stress area was in agreement with the actual fracture position.The OptiStrut software is used to optimize the topology of the fork,in which the maximum stress drops from 260.3 MPa to 213.8 MPa,and the structural shape of the fracture area increases by 1.62 mm.The result shows that the stress in the fracture region of the forked head is much less than the allowable stress of the material,and the machine of structure strength is improved.
