建立了包括脉冲电源模块和电磁轨道炮的全电路模型，实现了从电源放电至电磁轨道炮发射过程的全电路模拟。根据电源放电与洛伦兹力加速的耦合方程组，在电路模型内将电源的基本单元封装成子电路模块、弹丸受力运动模型转化为电路解耦模块，建立了针对24个基本单元组成的电源网络驱动串联型双轨增强电磁轨道炮的电路模型。将模拟结果与实验结果进行对比，电流模拟结果偏差2.6%，电枢出膛速度模拟结果偏差9.8%，模拟与实验结果基本一致，验证了模型方程和模拟方法的可靠性和合理性。

Based on the principle of electromagnetic railgun launch, a circuit model was developed and validated, the pulse forming units (PFU) and the progress of the railgun launch were included. The corresponding Pspice circuit code was developed to simulate the current of each pulse forming unit. Acceleration properties of the armature were also simulated by the Pspice analog behavioral modeling tools. The simulated railgun current and the armature velocity were 2.6% and 9.8% higher than the experiment results, i.e., the simulation and the experiment results were roughly consistent with each other. The model has provided valuable data which can directly benefit the design and operation of the series augmented railgun systems.
