摘要
矿用电磁先导阀中的本安型电磁铁部分是电信号转化为液压信号的枢纽,广泛应用在综采工作面的电液控制系统上.以矿用本质安全型电磁铁作为研究对象,介绍了本安型电磁铁的主要结构和工作原理,利用有限元分析软件Maxwell建立了电磁铁二维仿真模型,并仿真分析了本安型电磁铁动作过程中各部分磁场分布、动铁芯运动情况以及线圈电流变化情况,得出最优的安匝数;同时分析电磁铁的动态特性,分析其动态响应过程,并得出相应的最快动态响应频率.通过试验测试,对改进前后电磁铁性能进行对比分析,验证了优化设计的可行性.
Abstract
The intrinsic safety electromagnet part of the mine electromagnetic pilot valve is the hub of converting electrical signal into hydraulic signal,which is widely used in the electrohydraulic control system of fully mechanized mining face.Takes intrinsically safe electromagnet for mining as the research object,introduces the main structure and working principle of intrinsically safe electromagnet,establishes a two-dimensional simulation model of electromagnet using finite element analysis software Maxwell,and simulates and analyzes the magnetic field distribution of each part,the movement of moving core and the change of coil current during the operation of intrinsically safe electromagnet.The optimal ampere-turns are obtained.At the same time,the dynamic characteristics of electromagnet and its dynamic response process are analyzed,and the corresponding fastest dynamic response frequency is obtained.The feasibility of the optimized design is verified by the comparative analysis of the performance of the electromagnet before and after the improvement.
