    摘要:

    针对各参数对一种新型电磁作动器电磁力影响机理的问题,利用ANSYS软件建立了该电磁作动器的电磁力仿真计算模型,并对加工好的样机电磁力进行试验测量。结果表明,仿真计算结果能够与试验数据很好的吻合,最大相对误差仅为11.6%,从而验证了仿真模型的有效性。利用该仿真模型分析了齿高、线圈匝数、齿数、气隙、衔铁厚度和轭铁厚度等参数对电磁力的影响,揭示了其影响机理,为这种电磁作动器的进一步优化设计奠定了基础,对类似结构的电磁执行器的设计具有一定的参考价值。

    Abstract:

    The parameters affecting the electromagnetic force of a novel electromagnetic actuator are various, and influence mechanisms of them are still not clear. To solve this problem, the simulation calculation model of this electromagnetic actuator is worked out with the software ANSYS, and the electromagnetic force of processed prototype is measured by experiment. The precision of the simulation model is verified by comparing the experiment and simulation results, and the maximum deviation of electromagnetic force is 11.6%. According to the simulation model, the influence rules of several parameters to electromagnetic force are deeply analyzed, including tooth height, coil turns, tooth number, air gap, armature thickness and yoke thickness, and the influence mechanisms are disclosed. These results lay the foundation for further optimization of this electromagnetic actuator, and are helpful to the design of other similar electromagnetic actuators.
