针对当前武器系统试验分析评估存在难以进行大量试验,经典统计方法难以满足需求的状况,提出在小子样条件下对某型火箭弹射击密集度可靠性进行评估。根据地面模拟环境试验和飞行试验信息,利用二项分布确定火箭弹射击密集度可靠性的分布,使用计算机进行数值处理。在不降低试验要求的情况下,与经典方法相比,小子样理论大幅度地减少了飞行试验用弹量。
Aiming at the current situation that it is difficult to conduct a large number of experiments in the test analysis and evaluation of weapon systems and the classical statistical methods are difficult to meet the demand, the reliability evaluation of shooting intensity of a certain type of rocket projectile under the condition of a small sample is proposed. According to the ground simulation environment test and the flight test information, the binomial distribution is used to determine the distribution of the firing density reliability of the rocket and the numerical processing is carried out by using the computer. Compared with the classical method, the theory of small subsamples greatly reduces the amount of flight for flight test without reducing the test requirements.
