摘要: 寿命分布拟合是鱼雷装备可靠性研究的前提。以部队服役时间较长的某型鱼雷的失效数据为基础，利用极大似然估计方法和极小χ2估计拟合方法分别进行参数估计和拟合优度检验，确定最佳的寿命分布函数。通过实例比较研究，极小χ2估计拟合方法拟合效果更好，更能反映装备可靠性变化规律，具有更好的工程实践价值。
Abstract: The life distribution fitting is the precondition of the torpedo equipment reliability research. Based on the failure data of torpedo with long service life, the maximum likelihood estimation method and the minimum χ2 estimation fitting method are respectively used for parameter estimation and goodness of fit test to determine the best life distribution function. Through the example comparison, the minimum χ2 estimation fitting method fits better and can better reflect the variation rule of equipment reliability, and has better engineering practice value.
