为满足设计所要求的应力强度及变形,提出了一种基于ANSYS Workbench的优化设计方法。方法采用在Pro/E软件环境中建立轨轮式半自动双侧浇铸机的三维模型;利用ANSYS Workbench软件建立中凹架的有限元模型,针对中凹架在两种工作状态下的应力分布及变形量对其进行分段式结构优化;分析中凹架两翼伸长量与变形量之间的参数关系,对伸长量进行调整。优化后的车架体结构满足工况要求。
In order to meet the design requirements of the stress intensity and deformation, an optimization design method based on ANSYS Workbench is proposed. Methods The three-dimensional model of rail-wheel semi-automatic double-side casting machine was established in Pro / E software environment. The finite element model of the concave frame was established by using ANSYS Workbench software. According to the stress distribution and deformation of the concave frame under two working conditions, And then the section structure was optimized. The parameter relationship between the elongation of the two wings in the concave frame and the deformation was analyzed, and the elongation was adjusted. Optimized frame body structure to meet the conditions.
