鱼雷试验鉴定有关问题认识及改进方法

Discussion on Five Problems in Torpedo Test and Evaluation with Improvement Suggestions

针对鱼雷试验中存在或有争议的5个问题进行讨论同时提出改进方法:1)借鉴重复性故障统计方法,将重复性不合格项改为按一次统计,可解决试验计划安排差异而影响合格率;2)在目前定数试验的基础上,对"加试"的需求、原则进行了分析和确定,可弥补试验不充分不全面;3)根据样本量充分性要求和技术状态更改程度,对技术状态更改后是否"中断"试验和重试进行了分析和确定,可理清试验程序并避免闯关发生;4)根据ADC效能评估模型,对实航可靠度和能力进行界定,可解决目前实航可靠度和能力均重复判定不合格的问题;5)通过装载可靠度定义、装载试验前后检测一致性要求和实际使用的分析,对试后检测深度和广度进行明确。以上方法可为鱼雷试验大纲编制和修改完善相关评定标准提供参考,具有实际应用价值。

Five problems existing in the torpedo test and evaluation are discussed, and corresponding improvement methods are suggested as follows： 1） Using the statistical method of repeated failures for reference, the repeated unqualified items can be changed to a single statistics to eliminate the impact of the difference of test plans on the pass rate; 2） Based on the existing definite number test, the requirement and principle of the “adding test” are analyzed and determined to solve the inadequate and incomprehensive problems of a test; 3） According to the sufficiency requirement of sample size and the change condition of technical status, whether interrupt or retry the torpedo test after the technical status change is analyzed and determined to clarify the test procedure and avoid mistake; 4） The availability dependability capability（ADC） effectiveness evaluation model is employed to define the work reliability and the ability in sea trial, thus the problem that the work reliability and the ability are repeatedly judged to be unqualified can be solved; and 5） According to the definition of load reliability, the requirement of consistency before and after the torpedo load test, and the actual usage analysis of a torpedo, we clear the detecting depth and breadth after the test are clarified. The methods mentioned above may be applicable to compiling torpedo test outline and modifying the evaluation criteria.
