多电机驱动的双辊夹持旋压成形装置的动力学仿真
|
摘要
对双辊夹持旋压成形装置进给驱动系统进行了动力学分析,得到了装置进给驱动系统的动力学模型。利用多体动力学软件ADAMS和有限元软件ANSYS对多电机驱动的双辊夹持旋压成形装置进行了多刚体模型和刚柔耦合模型的动力学仿真,通过比较装置夹具和旋辊头运动轨迹的理论结果和仿真结果验证了所建立模型的正确性。仿真过程充分考虑了滑块与导轨之间的等效阻尼、刚度和摩擦等非线性因素以提高仿真精度。刚柔耦合模型仿真结果显示,旋辊头进给速度波动的幅度为±0. 065%,周期为0. 42 s,夹具进给速度波动的幅度为±0. 4%,周期为0. 71 s,表明丝杠的弹性变形会影响装置进给驱动系统的运动精度。
The dynamics analysis of feed drive system for double-roller clamping spinning device was carried out,and the dynamic model of the feed drive system was obtained. Then,the multi-rigid model and the rigid-flexible coupling model of the double-roller clamping spinning device driven by multi-motor were simulated by the multi-body dynamics software ADAMS and finite element software ANSYS,and the correctness of the established model was verified by comparing the theoretical results with the simulation results of the movement path of clamp and roller head. The simulation process fully considered the nonlinear factors such as equivalent damping,stiffness and friction between slider and guide rail to improve the simulation accuracy. The simulation results of the rigid-flexible coupling model show that the feed rate of the roller head fluctuates by ± 0. 065%,the period is 0. 42 s,the feed rate of the clamp fluctuates by ± 0. 4%,and the period is 0. 71 s,which indicates that the elastic deformation of screw affects the motion accuracy of the feed drive system of the device.
