Abstract

The Electromagnetic Aircraft Launch System (EMALS) offers significant benefits to the aircraft, ship, personnel, and operational capabilities. EMALS has such advantages as high thrust, good controllability, reusable, etc., as a launching motor, a double-side plate Permanent Magnet Linear Synchronous Motor (PMLSM) can provide high instantaneous thrust. This paper presents the design and analysis of the moving-magnet-type permanent magnet linear synchronous motor (PMLSM). A detailed analytical modeling based on Maxwell’s equations is presented for analysis and design of PMLSM with Halbach array. In order to improve the thrust characteristics of PMLSM, the structural characteristics and magnetic field are analyzed. The results show an enhancement in the motor performance. Finally, we have used 2-D nonlinear time-stepping transient finite element method to demonstrate validity of the analytical analysis and parametric search is used for multi-objective optimization of PMLSM. Using Finite Element Analysis (FEA), the effects of the parameters on the thrust and thrust ripple waveforms are analyzed.

电磁发射系统动磁式直线同步电机的设计与仿真

电磁飞机弹射系统(EMALS)为飞机、舰船、人员和作战能力提供了显著的优势。电磁弹射系统具有推力大、可控性好、可重复使用等优点，双极板永磁直线同步电机(PMLSM)作为发射电机，可以提供较高的瞬时推力。本文介绍了动磁体型永磁直线同步电动机的设计与分析。提出了基于麦克斯韦方程组的永磁同步电动机分析与设计的详细解析模型。为了提高永磁同步电动机的推力特性，对其结构特性和磁场进行了分析。结果表明，电机性能有所提高。最后，采用二维非线性时步暂态有限元方法验证了解析分析的有效性，并将参数搜索用于永磁同步电机的多目标优化。采用有限元分析方法，分析了各参数对推力和推力脉动波形的影响。
