基于APDL参数化建模的万向联轴器法兰叉架的优化设计
|
摘要
针对十字轴万向联轴器的法兰叉架在使用过程中出现断裂的问题,使用ANSYS的参数化设计语言APDL进行实体建模,通过对模型的应力分析,确定发生最大应力的位置。综合考虑该零件的加工工艺、结构、装配关系和成本等问题,确定了设计变量、状态变量和目标函数,并根据确定的变量和函数,使用一阶方法对法兰叉架进行优化设计。使实际工作情况下的最大应力值低于材料的等效应力值。最终的设计结果满足了实际使用要求,扩大了联轴器的使用范围,节约了成本。
In view of the fracture of the flange fork of the cross-shaft universal coupling, ANSYS APDL parametric design language was applied to conduct solid modeling. Through the stress analysis of the model, the location of the maximum stress was determined. Comprehensively considering the manufacturing technology, structure and assembly relationship and cost of the flange fork, the paper determined the design variables, state variables and objective functions. According to the determined variables and functions, it applied the first order method to optimize the design of the flange fork. After optimization design, the maximum stress in actual operation mode was lower than the equivalent stress of the material. The final design results met the actual service requirements, enlarged the service scope of the coupling and saved the cost.
