The Optimization of the Layout of Pedestal Key Components Based on ANSYS

摘要: 基座等承重件的强度性能直接关系机械系统安全性。以筋板式基座结构作为研究对象，其关键件筋的布置对基座结构强度性能影响较大，基于ANSYS WorkBench，以筋布置参数为优化变量，以结构强度与刚度为优化目标，在保证基座结构强度性能的基础上，对筋布置位置进行优化，实现基座筋理性化布局。结果表明，通过优化筋布置位置，基座结构的最大等效应力与最大变形量均降低。

Abstract: The strength of the load-bearing parts such as the pedestal is directly related to the safety of the mechanical system. Taking the ribbed pedestal structure as the research object, the design position of the key ribs has a great influence on the strength of the pedestal. Based on the ANSYS Workbench, taking the rib position parameters as the optimization variables, and taking the structural strength and stiffness as the optimization targets, the rib position is optimized to realize the rational layout of the pedestal ribs on the basis of ensuring the structural strength. The results show that the max equivalent stress and the max deformation are decreased by optimizing the position of ribs.
