摘要
首先描述了导弹质心定位设备测量误差分布研究的背景和质心定位误差模型,接着分析称重传感器误差量和的概率密度函数,在此基础上讨论了商的概率分布,并给出了分布通式,最后在一定约束条件下,给出导弹质心测量误差的概率分布图和逼近式.
The background of measurement error distrbution research and centroid locating error model of centroid locating equipment of missile are described firstly,and then the probability density of the sum of error random variable of weight sensor is analyzed.The probability distribution of error random variable quotient is suggested.Finally,the probability distribution chart and the approximate expression of centroid measurement error probability distribution are proposed based on constraint equation.
