To explore the influence of different caliber on the electromagnetic field and temperature field of railguns, an electromagnetic-thermal coupling analysis is carried out on three kinds of caliber railguns by Maxwell 3-D and ANSYS Workbench. The current density and temperature distribution on the contact surface between armature and rails of three kinds of caliber railguns are obtained, respectively. The calculation results show that the maximum current density and temperature of the small and medium caliber railguns appear on the contact surface, but the large caliber railgun appears to the armature throat. As the caliber increases, the current density and temperature on the contact surface have decreased significantly. The maximum current density of medium and large caliber railguns decrease by 13.7% and 35.5% compared with small caliber railgun, and the maximum temperature decrease by 38.8% and 50.1%, respectively. The temperature of the small caliber railgun rises fastest, which is 1.87 and 1.61 times that of the medium and large caliber railguns, respectively. The results can provide an important basis for the design of large caliber electromagnetic railgun.

不同口径电磁轨道炮电磁场和温度场分布特征

为探讨不同口径对轨道炮电磁场和温度场的影响,利用Maxwell 3-D和ANSYS Workbench对三种口径轨道炮进行了电磁-热耦合分析。分别得到了三种口径轨道炮电枢与钢轨接触面上的电流密度和温度分布。计算结果表明,中小口径轨道炮的最大电流密度和温度出现在接触面上,而大口径轨道炮出现在电枢喉部。随着口径的增加,接触面上的电流密度和温度都显着下降。中、大口径轨道炮最大电流密度比小口径轨道炮降低13.7%和35.5%,最高温度分别下降了 38.8% 和 50.1%。小口径轨道炮升温最快,分别是中、大口径轨道炮的1.87倍和1.61倍。研究结果可为大口径电磁轨道炮的设计提供重要依据。
