高压隔离开关自力型触指/触头结构仿真分析与优化设计

Finite Element Analysis and Optimization for the Assembly Structure of the Self-elastic Contacts

根据高压隔离开关自力型触指/触头机构服役工况,利用Solidworks软件建立自力型触指/触头有限元分析模型,在ANSYS Workbench集成开发环境(AWE)下对自力型触指/触头结构参数进行了优化设计,并分析了设计参数对自力型触指所受最大等效应力、剪切应力和变形的影响。结果显示:触头直径和触头摩擦行程与各响应变量之间均呈现出正相关关系,且触头直径的变化对响应变量的影响比触头摩擦行程对响应变量的影响更大。经多目标优化后,自力型触指/触头最佳结构参数为触头直径63.39 mm,摩擦行程15.24 mm。

In accordance with the service conditions of high voltage disconnector self-elastic contacts, a parameterization model of the assembly structure of the self-elastic contacts was established using the software Solidworks, and the optimal design of the structural parameters was performed on the integrated development platform-ANSYS Workbench. The relationships between input parameters and output parameters were analyzed, The results show that positive correlations exist between design variables and response variables, and contact diameter exhibits more significant influence on deformation and stress of the self-elastic contacts than contact displacement. After multi-objective optimization, the optimal parameters of the assembly structure of the self-elastic contacts are that contact diameter D=63.39 mm, and contact displacement S=15.48 ram. Analysis and optimization results may provide a theoretical basis for self-elastic contacts design.
