目前,矿用开关电磁铁在本质安全和功率的双重限制下,依靠传统的电磁铁优化设计思路难以进一步提高输出力的匹配特性.以矿用电磁先导阀上的电磁铁作为研究对象,针对其输出电磁力与负载反力匹配性差的问题,通过有限元分析了电磁铁结构参数对输出力特性的影响,并采用有限元分析与多目标遗传算法结合的优化思路,对电磁铁输出力特性曲线进行了矫正.实验表明,极靴内径与衔铁外径尺寸匹配关系对电磁力特性影响显著,优化后的电磁铁力位移特性水平段增加了一倍,与负载反力匹配性得到明显提升.研究成果对提高综采工作面的跟机效率奠定了元件基础.
Performance Analysis and Optimization of Switching Electromagnet for Mining
At present,it is difficult to further improve the matching characteristics of output force switching electromagnetic for mining by relying on the traditional electromagnet optimization design under the dual limitations of intrinsic safety and power.The electromagnet on the mine electromagnetic pilot valve is taken as the research object,aiming at the problem of poor matching between the output electromagnetic force and the load reaction,the influence of the structure parameters of the electromagnet on the output force characteristics is analyzed by finite element method,and the optimization idea combining finite element analysis and multi-objective genetic algorithm is adopted to correct the output force characteristic curve of the electromagnet.The experimentals show that the matching relationship between the inside diameter of the pole shoe and the outside diameter of the armature has a significant influence on the electromagnetic force characteristics.The horizontal section of the electromagnetic force displacement characteristic is doubled after optimization,and the matching with the load reaction force is obviously improved.The results have laid a foundation for improving the efficiency of mechanized mining face.
