摘要:

测试性作为装备通用质量特性之一,在舰船装备研制中逐渐受到重视,随着舰船综合电力技术的发展与应用,电力电子设备的作用越来越关键,针对当前舰船电力电子设备未考虑测试性设计的问题,研究了某型舰船逆变器的测试性设计与分析方法。首先分析了舰船逆变器的结构和工作特点,并结合维修保障要求对其进行层次划分；然后对舰船逆变器进行了故障模式、影响及危害性分析,并基于多信号流图模型,利用TEAMS软件建立了测试性模型；最后将测试性定量指标分配至可更换单元,为后续舰船逆变器的诊断设计等工作打下基础,并给同类型设备测试性技术的研究提供一些参考。

Abstract:

As one of the general quality characteristics of equipment, testability has been paid more and more attention in the development of ship equipment. With the development and application of ship integrated power technology, the role of power electronic equipment is becoming more and more critical. In order to solve the problem that the testability design is not considered in the current ship power electronic equipment, the testability design and analysis method of a certain ship inverter is studied. Firstly, the structure and working characteristics of the ship inverter are analyzed, and the inverter is also divided into different levels according to the maintenance guarantee. Then the failure mode, effect and criticality analysis (FMECA) of the ship inverter are conducted, and based on the multi-signal flow diagram model, the testability model is established by using the TEAMS. Finally, the testability quantitative index is assigned to the replaceable unit, which lays a foundation for the subsequent diagnostic design of the ship inverter, and provides some references for the research on testability technology of the same type of equipment.
