摘要
针对现有引信自适应延期起爆方法复杂度、成本较高或无法计算弹丸的出靶速度造成炸点散布较大的问题,提出了由双阈值开关估计出靶速度的自适应延期控制;该方法是引信根据薄、厚双簧片阈值开关侵彻过程中的动态响应信息计算弹丸的出靶速度,根据出靶速度设定引信延时起爆时间;仿真计算和外场试验表明设计的双簧片阈值开关可以满足一定范围内炸点自适应起爆控制,炸点可满足战标要求。
Targeting at such problem as high spread of burst point caused by complexity of fuse-detonating method for existing adaptive delay, higher cost or imponderable target speed, therefore, adaptive delay control on target speed estimated by dual-threshold switch was proposed. This method was to calculate the projectile' s target t speed on the basis of the thin and thick double reed during the penetration process of threshold switch. The simulating calculation and field test show that the designed double reed threshold switch can satisfy the burst point' s adaptive control from a certain range. Also, the burst spot meets the standard reauirements.
