摘要
鉴于现有复进机结构复杂,难以满足复进过程实时可控性的要求,提出一种基于双初级圆筒型永磁同步直线电机(Double Primary Tubular Permanent Magnet Synchronous Linear Motor,DP-TPMSLM)原理的电磁复进机。通过分析复进过程各部件受力情况,建立复进运动微分方程,明确了所需复进机力的大小;对于DP-TPMSLM,齿槽效应和端部效应的解耦以及端部结构的改进,有效地抑制了定位力的基波和二次谐波,显著降低了电机的推力波动,并通过小型样机实验得以验证;进一步地,提出基于DP-TPMSLM原理的电磁复进机,并将其应用于车载炮系统中,开展了联合仿真研究。实验和仿真结果表明:与未改进的结构相比,改进后的DP-TPMSLM的定位力降至465.9 N,降低了34.4%;同时,所提电磁复进机能够实现对复进过程的实时控制,从根本上解决了炮尾和摇架之间的碰撞问题。
Considering the complex structure of existing recuperators,which often struggle to meet the real-time controllability requirements of recuperation process,this paper proposes an electromagnetic recuperator based on the principle of a double primary tubular permanent magnet synchronous linear motor(DP-TPMSLM).The differential equations governing the recuperation motion are established by analyzing the forces acting on each component during the recuperation process,and the magnitude of the required recuperator force is clarified.For DP-TPMSLM,the decoupling of cogging and end effects and the improvement in the end structure,the fundamental and second harmonics of the detent force are effectively suppressed,resulting in a significant reduction in thrust fluctuations,as verified by the experiments on a small-scale prototype.Furthermore,an electromagnetic recuperator based on the principle of DP-TPMSLM is proposed,and a co-simulation study is made on applying it to a vehicle-mounted artillery system.The experimental and simulated results demonstrate that the detent force of the improved DP-TPMSLM is reduced to 465.9 N,which is educed by 34.4%decrease compared to that of the unimproved structure.Meanwhile,the proposed electromagnetic recuperator effectively achieves the real-time control of recuperation process,fundamentally addressing the issue of collision between the breech ring and the cradle.
