摘要
以液压支架电磁先导阀上的电磁铁作为研究对象,分析先导阀电磁铁的工作特点,运用Maxwell有限元软件对电磁铁进行仿真分析,得到电磁铁的静态输出特性,发现衔铁长度在28 mm时效果最佳;将静态特性仿真分析结果导入AMESim中,建立电磁铁驱动负载动态系统模型,实现电磁-液压-机械的联合仿真分析,得出电磁铁气隙、安匝数、电感、输出力之间的关系,发现初始气隙的大小应低于0.8 mm,以提升电磁铁的承载能力。
Taking the electromagnet in the solenoid pilot valve of the hydraulic support as the research object,the working characteristics of the electromagnet was analyzed.Maxwell finite element software was used to simulate the electromagnet,and the static output characteristics of the electromagnet were obtained.And it is found that the effect is the best when the armature length is 28 mm.By introducing the static characteristic simulation analysis results into AMESim,the dynamic system model of electromagnet under driven load was established,the co-simulation analysis of electromagnet,hydraulic and machinery was realized,and the relationships among electromagnet air gap,ampere turns,inductance and output force were obtained.It is concluded that the size of initial air gap should be less than 0.8 mm to improve the bearing capacity of electromagnet.
