轻武器寿命可靠性模型研究

为轻武器寿命可靠性评定提供理论依据,运用经典的可靠性理论,将轻武器装备寿命试验归结为可修复系统的有替换定时截尾试验,通过分析某型机枪的寿命试验数据,对母体寿命可能的分布类型作出假设,选择χ2检验法对假设进行拟合优度检验,利用最小二乘法得出对应分布的线性相关系数,通过比较确定母体分布类型,建立了该型机枪寿命的可靠性数学模型,对同类轻武器装备的可靠性指标评定提供了一定的参考。

Research on the Reliability Model of Light Weapons Life

To provide a theoretical basis of the reliability evaluation for light weapons life,using the classical eliability theory,put the light weapons life test down to a replacement time censored test of the repairable system,through the analysis on life test data of a certain type of machine gun,make assumptions about the possible type of distribution of maternal life, select Chi-square test method to make the goodness of fit test for the hypotheses,compute the linear correlation coefficient of distribution by the least square method,confirm parent distribution types through the comparison,build reliability mathematics model for this type of machine gun life,to provide a certain reference for the reliability index evaluation of the similar light weapon equipment.
