电磁铁利用电磁力作机械功从而将电能转换为机械能,其结构参数的优化设计非常重要。本文以双行程螺管式电磁铁为研究对象,提出一种AnsysMaxwell与ADAMS联合仿真的建模方法。首先,采用磁路法计算出静态吸力公式,为参数设计提供依据;然后,在Maxwell有限元软件中,建立双行程电磁铁的三维模型,仿真得到其静态特性,耦合电压平衡方程和达朗贝尔运动方程,利用能量增量法得到动态吸力位移曲线;建立ADAMS仿真模型,导入动态吸力得到位移时间曲线,与实验结果相比误差在5%以内,验证了Ansys Maxwell与ADAMS联合仿真的可靠性,为电磁铁的动态分析和结构参数设计优化提出了一种新方法。

The electromagnet uses electromagnetic force to make mechanical work to transform electrical energy into mechanical energy,and the optimization of its structural parameters is very important.In this paper,a modeling method of Ansys Maxwell and ADAMS joint simulation was proposed based on a double stroke solenoid electromagnet.First,the static suction formula was calculated by analytic method,which provided the basis for the design of parameters.Then,the three-dimensional model of the double stroke electromagnet was established in the Maxwell finite element software to get the static characteristics.By coupling voltage balance equation and the Darren Bell motion equation,the dynamic suction displacement curve was obtained with the energy increment method.Thirdly,by constructing the ADAMS mechanical model and introducing the dynamic suction to the model,displacement time curve was simulated.Within 5%error compared with the experimental results,the reliability of the joint simulation between Ansys Maxwell and ADAMS is verified and a new method is proposed for the dynamic analysis and structural parameters optimization of the electromagnet.
