摘要
针对电动力鱼雷试验数据较少的问题,提出基于修正极大似然与序贯压缩相结合(CMSR)的电动力鱼雷实航工作可靠度综合评估方法。通过分析串联系统可靠性评估方法优缺点,结合改进型电动力鱼雷一次电池数量偏少、各分系统试验样本量不同的特点,运用CMSR评估模型,提出三串联系统可靠性试验方案和评估方法,可得到较高置信水平的全雷实航工作可靠度评估结果,具有较好的实用性。
Aiming at the problem of less test data for electric power torpedoes, this paper proposes an assessment method of electric power torpedoes working reliability in a sea trial based on the combined modified maximum likelihood(CMML) and sequential reduction(SR) method(CMSR). By analyzing the advantages and disadvantages of the reliability assessment method of the series system, combined with the improved electric power torpedo’s characteristics of less actual sailing data of primary batteries and different test samples of each subsystem, this paper proposes a three-series reliability test scheme and assessment method using the CMSR assessment model. This method can obtain a higher confidence level of assessment results for torpedo working reliability in sea trials and has better practicability.
