摘　　要：为了分析增强型4轨平面串联直线驱动装置的转化效率及其能量分布,选择场路协同分析方法,基于MATLAB Simulink和COMSOL平台,建立了脉冲大电流直线驱动装置模型。仿真结果通过与试验数据进行对比,验证了计算模型的可靠性。该模型可实现驱动装置电感梯度和电阻梯度等重要参数和驱动装置的转化效率、出膛速度以及驱动装置能量分布情况的仿真计算,为结构优化提供了高效可靠的计算模型。根据计算结果可以发现,驱动装置的电气参数不仅受电流频率影响,还与电流幅值相关;驱动装置的输入能量中,分布在轨道的能量最多,约50%,绝大部分能量转化为了焦耳热,约54.15%,仅27.76%的能量转化为电枢的动能。In order to obtain the efficiency and energy distribution of 2-turn plane augmented linear drive,the field circuit collaborative analysis method was selected,and the pulse high current linear drive model was established based on the MATLAB Simulink and COMSOL platform.The reliability of the calculation model was verified by the experiment data.The model can be used to simulate the important parameters such as inductance gradient and resistance gradient of the driving device,as well as the conversion efficiency,exit velocity,and energy distribution of the drive,which provides an efficient and reliable calculation model for structural optimization.According to the calculation results,it can be found that the electrical parameters of the drive are not only affected by the current frequency,but also related to the current amplitude.Among the input energy of the drive,the most energy distributed in the rail is about 50%,most of the energy is converted into Joule heat,about 54.15%,and only 27.76%of the energy is converted into the kinetic energy of the armature.
