基于Ansys Workbench的等壁厚螺杆钻具定子切削仿真分析

摘要

针对等壁厚螺杆钻具定子螺旋啮合线型在电解加工时存在的稳定性、电极制造和排污方面的问题，提出一种利用仿真分析可指导设计的深孔拉削方法。文中对某切削状态时的拉力和转矩进行理论计算，选用Pro Engineer软件实现建模，再导入到Ansys workbench软件中进行虚拟仿真分析，分别得到等壁厚螺杆钻具定子某切削状态时的拉力和转矩，并与实际试验效果进行对比。结果表明：该方法有效地提高了工程应用领域中数控深孔螺旋拉削成套设备的设计能力，使成套设备的设计更合理、高效。%Aiming at problems of stability, electrode manufacturing and pollution discharge of the equal wall thickness screw drill stator spiral gearing line, put forward the deep hole boring method based on simulation analysis design. The paper carry out theoretical calculation for pulling force and torque in cutting state, select Pro Engineer software to establish model, then input it into Ansys workbench software for virtual simulation analysis, acquire pulling force and torque of equal wall thickness screw drill stator in cutting state, at last compare it with real test performance. The results show that: the method can effectively improve design ability of NC deep hole spiral boring complete sets of equipment, and make the equipment design more reasonable and higher efficiency.
