基于Ansys Workbench的不同截面型式自力型触指/触头配合结构优化设计
Gaoya dianqi, 2017 采用Cu-Cr合金材料,利用Solidworks建立自力型触指的矩形和W型截面触指/触头配合结构三维模型;通过DOE分析选取设计变量;运用Ansys Workbench的参数目标驱动优化对其结构参数进行了优化仿真。2种不同截面配合结构的最大应力和最大变形量的对比显示:随着触头直径、触指厚度以及摩擦行程的增大,各响应变量与之成正比例关系,且触头直径与摩擦行程对响应变量的影响比触指厚度的变化对响应变量的影响更大。经过多目标驱动优化后,矩形触指的最大变形量为6.6 mm,而W型触指最大变形量为2.6 mm ...
