摘要
针对实验室电磁轨道炮电枢与轨道之间的高速相对运动导致的电枢与导轨之间不可靠接触、损伤电枢及导轨等问题,提出了一种改良的电枢—轨道接触方案。方案使用了铝基液态复合电枢和挤压式轨道,轨道以STM32微控制器为控制核心,利用K型热电偶以及MAX6675模块对电磁炮馈电发射后的温度进行采集,通过L298N模块驱动步进电机调整炮口间距。实验证明:本设计方案有效地缓解了由于轨道法向负荷不足导致的电枢转捩问题。
Aiming at the unreliable contact between armature and guide rail caused by the high-speed relative motion between armature and track of electromagnetic track gun in laboratory,an improved armature-track contact scheme is proposed.The scheme uses aluminum-based liquid composite armature and extrusion track.The track is controlled by STM32 microcontroller.K-type thermocouple and MAX6675 module are used to collect the temperature of electromagnetic gun after feeding and launching.The muzzle spacing is adjusted by L298N module driving stepper motor.Experiments show that the design scheme can effectively alleviate the armature transition problem caused by the lack of normal rail load.
