摘要
针对目前航母用舰载机蒸汽式弹射器效率低等问题,提出基于双边直线感应电机的舰载机电磁弹射器。通过舰载机动力学方程分析其弹射技术要求,从物理模型和等值电路两方面分析弹射器驱动源长初级双边直线感应电动机,推导弹射所需电磁推力与设计参数量的关系,并给出具体直线电机设计参数。利用计算机应用软件仿真分析次级长度、电机极距、线圈匝数等设计参数对电磁推力输出影响,同时建立直线电机有限元模型,验证理论计算的有效性。通过理论推导和仿真验证,为双边直线感应电机在舰载机电磁弹射方面研究提供理论依据。
To solve the low efficiency of current steam catapults of carrier-based aircraft, the authors proposed the electromagnetic catapult of carrier-based aircraft using double-sided linear induction motor. The authors analyzed the technical requirements of the catapult of carrier-based aircraft through the kinetic equations, analyzed the drive source of the catapult- long primary double-sided linear induction motor – through the physical model and equivalent circuit, derived the relationship between required thrust and the design parameters of the electromagnetic catapult, and provided specific design parameters. Using computer simulation analysis, the authors analyzed the impact of secondary length, motor pole pitch, turns and other design parameters on electromagnetic thrust output, and established the finite element model to verify the validity of theoretical calculation. Through theoretical analysis and simulation, the authors provided a theoretical basis for research for linear induction motor of the catapult of aircraft carrier.
