高频响阀用比例电磁铁仿真优化及制作

Simulation Optimization and Production of High-Frequency Valve with Proportional Solenoid

工业上使用的阀用电磁铁普遍存在能耗高,响应慢等缺点,降低了电磁铁的使用寿命,提高了生产成本。以4WRPH6高频响比例电磁铁为研究对象,结合电磁场有限元分析理论,准确地建立比例电磁铁三维有限元模型,优化网格划分,探讨比例电磁铁线圈匝数、电感值、输出力以及磁漏之间的相互关系,并从仿真结果中选出最优参数。绕制优化后的线圈并替换原有线圈,实验验证得出优化结果。研究结果表明,选择标称直径为0.62mm,漆包线最大外径为0.67mm的铜线最佳,其匝数为388匝,槽满率为78.68%。上述线圈优化方法具有重大的工程实践意义。

The valve electromagnet used in industry generally has high energy consumption and low efficiency,which reduces the life of the electromagnet and raises the production cost.Taking 4 WRPH6 high frequency proportional electromagnet as the research object,and combined with the theory of electromagnetic field finite element analysis,a three-dimensional accurate proportional finite element model of electromagnetic valve wass set up,the mesh generation was optimized,and the relationship between proportional electromagnet coil number of turns,inductance and output force as well as the magnetic leakage was discussed.And the optimal parameters were chosen from the simulation results.The optimized coil was replaced with the original coil,and the results were obtained by experiment.The results show that the diameter of the nominal diameter is 0.62 mm,the maximum diameter of the enameled wire is 0.67 mm,the number of turns is 388 turns,and the filling rate is 78.68%.The coil optimization method has great practical significance.
