摘　　要：为有效解决轨道炮电枢熔化问题,提出一种基于炮口分流降低接触电阻焦耳热功率的电枢熔化抑制方法。分析了电枢熔化形成机理,设计了电阻器、电感器和电容器炮口分流3种降低接触电阻焦耳热方案,仿真计算了3种炮口分流方案接触电阻焦耳热功率和产生量,分析了3种方案对电枢熔化的抑制效果。结果表明:电阻器和电感器炮口分流方案可使接触电阻焦耳热产生量显著降低,能够抑制电枢熔化,但是需要增加输入电流补偿炮口分流对电枢电磁力的影响;电容器炮口分流效果十分有限,起不到抑制电枢熔化的作用。For effectively solving the problem of the armature melting, this paper proposed suppress method of armaturemelting based on muzzle shunt for reducing contact resistance Joule heat. The mechanism of armature melting is analyzed,design three reducing contact resistance Joule heat schemes: resistor muzzle shunt, inductance muzzle shunt, and capacitormuzzle shunt. The heat power and output of 3 schemes are simulated and calculated, and analyzed suppress effect of 3schemes on armature melting. The results show that the resistor muzzle shunt scheme and inductance muzzle shunt scheme cansignificantly reduce the contact resistance of Joule heat, thereby suppressing the armature melting, while, these two schemeshave to increase the input current to compensate the effect of muzzle shunt on armature electromagnetic force. The effect ofcapacity muzzle shunt scheme is very limited. Thus, the capacity muzzle shunt scheme cannot suppress armature melting.
