摘　　要：为了提升直线感应加速器的发射性能,引入补偿器件以改善磁场分布。基于电磁场理论,建立直线感应加速器的数学模型,通过场路耦合模型进行有限元仿真,得到速度、位移及作用力的参考值,进一步地通过设置一种补偿器件用于提升发射效率,对比分析补偿器件在不同厚度、材料以及电枢不同装填位置时对炮口电枢速度的影响,从而得出一般设计策略。研究表明通过引入高磁导率低电导率的补偿器件可以显著提高发射效率,对直线感应加速器的参数选择和方案设计具有指导意义。In order to improve launching performance of linear induction accelerator （LIA）, a compensator was introduced to optimize the distribution of magnetic field. The mathematic model of LIA was established based on electromagnetic field theory, the reference values of driving force, velocity and displacement were obtained by finite element analysis of field-circuit coupling mo- del, and a compensator was introduced to improve launching efficiency. The influence of com- pensator on muzzle velocity in different thickness, materials and loading positions were com- pared and typical design strategies were obtained. The analysis results show that the compen- sator with high magnetic permeability and low conductivity can significantly improve launching efficiency. The study can provide a certain reference for parameter selection and design of LIA.
