Abstract

Based on the mathematical model of the current filament method in induction coil gun, the factors of inductance matrix in the mathematical model are studied. The schemes of sparsing mutual inductance gradient matrix and inversing the matrix by block iterative and order reduction are used to shorten the time of the current filament method simulation model while maintaining reliability. In order to verify the validity and reliability of the improved current filament simulation model, the 25-stage, 50-stage and 100-stage induction coil guns are taken as the research objects respectively. The results of the current filament method simulation model before and after improvement are compared. The effectiveness and reliability of the improved current filament method are verified. In order to further study the influence of the sub-schemes, the 50-stage and 100-stage induction coil guns are taken as the research objects, and the influence of each sub-scheme is analyzed by the control variable method. It can be seen from the results that inversing the matrix by block iterative and order reduction is better than sparsing mutual inductance gradient matrix in shortening the time of the simulation model.

基于电流灯丝法的多级线圈枪模型加速计算与分析

基于感应线圈枪电流灯丝法的数学模型，研究了数学模型中电感矩阵的影响因素。采用稀疏互感梯度矩阵、块迭代求逆矩阵和降阶等方法，在保证可靠性的前提下，缩短了当前灯丝法仿真模型的时间。为了验证改进的电流灯丝仿真模型的有效性和可靠性，分别以25级、50级和100级感应线圈炮为研究对象。对改进前后的现有丝法仿真模型的结果进行了比较。验证了改进电流灯丝法的有效性和可靠性。为了进一步研究各子方案的影响，以50级和100级感应线圈炮为研究对象，采用控制变量法对各子方案的影响进行分析。从结果可以看出，在缩短仿真模型的时间方面，采用分块迭代法和降阶法求逆矩阵优于稀疏互感梯度矩阵。
