摘要： 在圆柱滚子双盘直槽研磨加工中，为提高滚子的加工效率，满足滚子连续进料的要求，设计了一种将电磁能转化为机械能的电磁推进装置，将它运用到圆柱滚子的研磨加工送料中。对圆柱滚子电磁推进装置的结构设计，通电状态下磁场的分布、磁场运动情况进行理论分析后，利用ANSYS Maxwell电磁场仿真软件对装置的二维模型进行仿真，查看磁场的分布及运动情况，并得出在不同电源激励条件下各滚子受力及整列滚子受力情况。仿真结果表明：装置通电后，内部会产生沿其轴线方向作周期性运动的行波磁场，并能够向滚子提供方向一定、大小可调的电磁推力，可以满足滚子研磨加工中连续推料的要求。随着电源电压和频率的增大，电磁推力也增大，推力调节方便。搭建了圆柱滚子电磁推力测量实验平台，对比了相同激励条件下仿真和实验所得电磁推力。实验结果表明：滚子受到的电磁推力随电源电压和频率的增加而增加，在相同的激励条件下，实验测得结果与仿真计算结果接近，验证了仿真结果的准确性。该装置可以实现滚子连续进料，具有较大的实际应用价值。
Abstract: When using the method of double-disc straight groove grinding in the process of machining rollers, in order to improve the processing efficiency of rollers and meet the requirements of continuous feeding of rollers, a kind of propulsion device is designed which can convert electromagnetic energy into mechanical energy and apply to lapping processing of cylindrical roller. The structural design of the device, the magnetic field distribution and motion condition when the device was under the energized condition were analyzed. ANSYS Maxwell, one kind of electromagnetic field simulation software was used to simulate the 2D model of device. The distribution and motion of the magnetic field were observed, the force operated on each roller in the device and the whole force state under different excitation conditions were obtained. The simulation results showed that: when the device was under energized condition, it would produce travelling-wave magnetic field doing periodic motion along the axis direction, and provide electromagnetic thrust with certain direction and adjustable size, which could meet the requirement of continuous feeding in roller lapping. With the increase of voltage and frequency, the electromagnetic thrust would also increase, and it was convenient to adjust thrust. An experimental platform for measuring electromagnetic thrust was built. Electromagnetic thrust obtained under the same excitation condition through simulation and experiment was compared. The experiment results showed that, the whole electromagnetic thrust acting on rollers would increase with the increasing of voltage and frequency. Under the same excitation condition, the experiment results were close to the simulation results, which verified the accuracy of the simulation results. The device can realize the continuous feeding of rollers and has great practical value.
