介绍了一种新型密闭容器料位监测装置的设计方案。基于ANSYS平台对监测装置的关键零部件清洗轮进行静力学分析,结果显示存在结构冗余。为获得更好的动力学性能,采用拓扑优化和多目标尺寸优化相结合的设计方法,以最大变形量、最大等效应力作为约束条件,对清洗轮进行了以减轻总质量为目标的结构优化设计研究。分析结果表明:与原设计方案相比较,优化圆整后的清洗轮总质量为0.998 kg,相比优化前的1.526 kg,质量减少34.60%;最大等效应力37.215 MPa小于材料的许用压应力110 MPa,说明力学性能满足要求;最大整体变形量为0.023 mm,满足最大整体变形0～0.25 mm的设计需求。

This paper introduced a new design scheme of the material position monitoring device for the closed container.Based on the ANSYS platform,static analysis was performed on the key parts cleaning wheel of the monitoring device,and the results showed that there was structural redundancy.In order to obtain better dynamic performance,a topological optimization and multi-objective size optimization combined design method is adopted,the cleaning wheel is relieved with the total deformation maximum and the equivalent stress maximum as constraint conditions,search on structural optimization design with...
