摘　　要：建立了比例电磁铁有限元仿真模型,利用Ansoft Maxwell2D电磁场有限元仿真软件对衔铁长度、衔铁上推杆孔的深度和孔径、衔铁前端和尾部倒角及圆角对比例电磁铁行程-力特性的影响进行了仿真计算。结果表明:衔铁长度对比例电磁铁工作行程内电磁力大小和水平程度有比较明显的影响;推杆孔的深度和孔径越大,靠近吸合面的电磁力越小;衔铁前端倒角对比例电磁铁行程-力特性影响比较明显;衔铁前端圆角、尾部倒角和圆角对比例电磁铁行程-力特性的影响很小;衔铁前端加工圆角可以增大比例电磁铁工作行程,但这是以减小工作行程内电磁力为代价的。It establishes a ratio electromagnet finite element simulated model,and use the Ansoft Maxwell2 Delectromagnetic field finite element simulation software to make stimulation calculation on the influence of armature length,pushrod＇s depth and aperture of armature,the armature front and rear＇s chamfer and circular bead on ratio electromagnet stroke-force characteristics.The results show that：the length of the armature have significant effect on the electromagnetism size and level degree in the working process of the ratio electromagnet.The larger of the depth and aperture of pushrod hole,the smaller of the electromagnetism that nears the actuation surface.The front chamfer of armature has significant effect on ratio electromagnet stroke-force characteristics.The front circular bead and rear chamfer and circular bead has little influence on ratio electromagnet stroke-force characteristics.Armature front processing circular bead can increase ratio electromagnet stroke-force,but it is at the cost of reducing electromagnetism within the working operation.
