Based on ANSYS Workbench 3D modeling, we carried on finite element analysis to tool, and used the method of goal driven optimization to optimize the rotary tool. The optimization proves that the optimized maximum equivalent stress is 544.14 MPa, the quality is less, and the optimized rotary tool size is more reasonable. So it provided reasonable and scientific reference frame to the structural design of rotary tool.展开更多
