摘要
大推力电磁弹射技术是利用大功率直线电机的电磁推力驱动载荷在短时间、短行程内迅速达到超高速度的新型发射技术。针对大质量载荷高速度垂直发射系统需求,通过方案对比,采用多重化双边型永磁同步直线电机作为动力方案,并针对功能需求,设计了能够满足多规格载荷连续发射的自适应电磁发射系统样机、直线电机样机电磁方案及其配套变流器,并通过实验室内小型水平式双边型永磁同步直线电机实验平台验证了直线电机的力能指标与电磁发射控制功能。
The main idea of the high-thrust electromagnetic ejection technology is driving a load to a super-high speed in short time within limited distance with the high-power linear motor’s electromagnetic thrust as the motivation.According to the requirements of high-speed vertical launching system with large-mass load,a multiple double-side permanent magnet synchronous linear motor scheme is adapted based on the comparison of several different types of motors and structures.In order to satisfy the functional requirements,a prototype scheme of a self-adaptive electromagnetic launching system,including the electromagnetic scheme of the linear motor prototype and its supporting converter,is designed for the continuous launching of multi-specification load.Finally,the force and energy indicators and electromagnetic launching control function of the linear motor are verified by a small horizontal double-side permanent magnet synchronous linear motor experimental platform in the laboratory.
