    摘要:

    为了在液压系统中能够利用较少的能耗使其获得较高的液压能实现对外界做功,提出一种大吸力、长行程的液压系统专用电磁铁,设计出一种新式的双线圈电磁铁。阐述电磁铁的结构及工作原理,利用工程磁场有限元方法建立数学模型,采用静磁场法仿真并绘制了电磁铁相关参数变化的力-位移特性曲线,得到了电磁铁的优化结构及其磁感应强度云图。结果表明:利用仿真可获得电磁铁合理的结构和工作特性,可获得到较大的电磁力与较好的磁感应分布情况。该电磁铁结构简单、行程大、输出力大,其仿真结果能够对电磁铁结构设计与工作特性分析提供参考,大大缩短了电磁铁设计与开发的周期。

    Abstract:

    In order to achieve doing work by using less energy consumption to obtain higher hydraulic energy on the outside of the hydraulic system,a high power and long gap special electromagnet in hydraulic system was proposed, the new doublecoil electromagnets was designed.The structure and working principle of the electromagnet were described.The mathematical model was established by using finite element method of engineering magnetic field.According to static magnetic field simulation, the force and displacement curves with variation parameters of electromagnet were drawn, the optimal structure of the electromagnet and the cloud chart of the magnetic induction intensity were obtained.The results show that using the simulation, the reasonable structure and working characteristics of the electromagnet can be obtained.The powerful electromagnetic force and the better magnetic induction distribution can be gained.The electromagnet has the characteristics of simple structure, large stroke and large output force.The simulation results provide reference for the design of the electromagnet structure and the analysis of the working characteristics.It can reduce the cycle of electromagnet design and development.
