摘　　要：通过对带有截锥形铁芯和挡铁的直流螺管电磁铁磁路的分析,介绍了其磁路计算(包括磁阻、磁通以及吸力等)的方法。基于Matlab强大的数值计算能力及其丰富的函数库,通过Matlab编程实现了直流螺管电磁铁静态吸力特性的计算和特性曲线的绘制,并给出了程序流程图。另外,给出了3种不同结构电磁铁的吸力特性的计算实例。In this paper, the magnetic circuit of DC solenoid electromagnet with frustum magnet core and ar- mature was analyzed,and the method of magnetic circuit calculation( including the calculations of the magnetic re- sistance ,of the magnetic flux and of the attraction,etc.)was described.Based on the powerful numerical value computation capability and the plentiful function libraries of Mulat,the calculation of the static attraction charac- teristic of DC solenoid electromagnet was implemented and its characteristic curve was plotted by programming in Matlab, and the program flow chart was given.The calculation examples of the attraction characteristies for three different type electromagnets were given.
