以气动单轨吊变速装置中的拔叉为研究对象,根据联接形式和装配空间设计了拔叉的基本结构,根据受力状况确定了基本尺寸,建立了力学模型,同时在Pro/E中建立了三维立体模型,在ANSYS Workbench中进行了有限元模拟仿真试验,分析了静力学应力应变特性,并进行了结构优化设计.“,”The basic structure of the drawing fork is designed according to the connecting form and the assembly space. The basic dimensions are determined according to the force, and the mechanical model was established. At the same time, a three-dimensional model was established in Pro/E, and a finite element simulation experiment was conducted in ANSYS Workbench. The statics stress and strain characteristics were analyzed and structural optimization design was carried out.
