摘　　要：在电磁轨道炮的发射过程中产生大量热量,引起炮膛内部温度突变是导致导轨材料失效的重要原因,从轨道炮系统的温升来源和热的形式两个方面介绍了电磁轨道炮膛内热效应的研究现状,对电接触理论和轨枢界面焦耳热、摩擦热、电弧热等不同机制产生的热进行了分析和归纳。In the electromagnetic rail gun firing process,it produces a lot of heat,and the heat caused to the sudden change in temperature is an important reason leading to the failure of rail materials. In this paper,the current research situation of the thermal effect in the orbital bore of the orbital gun is briefly introduced from the two aspects of the temperature rise source and the thermal form of the rail gun system.The thermal contact mechanism and the heat generated by Joule heat,frictional heat was analyzed and conclude.
