摘要
为探寻电磁炮运动参数的变化规律,对等离子电枢运动过程进行了理论分析,建立了电枢速度和电流之间的数学模型。模型中考虑了电枢运动中所受的主要阻力,包括等离子体的粘滞阻力和惰性阻力。另外,通过多次的仿真数据与实验结果比较,选取了能够较好地符合实际电枢运动过程的弧压数据。建立的仿真模型应用于实际系统进行预测,预测结果与试验结果相吻合。
In order to explore variable law of EM gun movement parameters, the motion process of plasma armature was analyzed in theory, and the mathematic model between armature speed and current was established. Main resistances in armature motion were considered in model, they were plasma viscous drag and inertial drag. In addition, compared simulation data with experimental results in many times, the arc voltage data that can fairly reflect the armature motion status were selected, and the established model was applied in actual system to predict parameters. The result showed that the predicted results were coincide with the tested results.
