摘　　要：针对自由活塞式内燃机直线运动的特点,选用电磁铁作为它的起动机构。在此基础上,针对电磁铁特性建立数学模型,再利用Matlab/simulink为其搭建一个简单而通用的动态仿真模块,通过改变仿真参数,探究影响电磁铁动态特性的因素,为自由活塞式内燃机起动机构的设计提供理论参考。According to characteristics of linear motion of the free piston engine, an electromagnet was used as its starting mechanism. A general and simple simulation model of electromagnet was given based on the simulink function of Matlab software. The factors which affected the dynamic property of electromagnet were found by changing the parameters. The simulation provided theoreti- cal foundations for designing of starting mechanism of the free piston engine.
