行进间射击复合射击门随机穿越特征量的分析

摘要

以高速行进间射击为背景,分析了火炮身管在路面谱等激励下振动角速度随时间的分布及其与身管角度误差过程之间的关系,借助均方导数概念给出了求解身管振动角速度过程的方法,并以此为基础分析了位置-速度复合射击门的随机穿越特征,仿真结果表明,复合射击门相对于简单射击门有更好的随机穿越特征指标.%The time-based distribution of vibration angular velocity of a barrel excited by the road irregularity, etc. and the relationship between it and angular error process of the barrel were analyzed in the context of high-speed gun firing on the move. A method to derive the angular velocity process of barrel was proposed based on mean square derivative, and the random cut-through characteristics of location-speed complex firing gate was analyzed. The simulation results show that complex firing gate, compared to simple firing gate, has the better indicators of random cut-through characteristics.
