Application of Reliability Enhancement Test for Torpedo Products
-
摘要: 可靠性强化试验通过给产品施加步进应力以快速激发出产品故障, 具有试验周期短、暴露故障快的特点, 是提高产品固有可靠性水平的有效手段。针对可靠性强化试验在鱼雷产品上应用较晚、还未形成方法体系的问题, 文中结合鱼雷产品特点, 基于可靠性强化试验技术, 给出可靠性强化试验在鱼雷产品上应用的具体方法, 包括可靠性强化试验的试验流程、参试产品的确定、环境应力分析及典型试验剖面等内容。通过工程应用表明该方法合理可行, 能够为鱼雷可靠性强化试验提供参考。Abstract: The reliability enhancement test induces step stress to stimulate the failure of products. It has a short period and reveals failure rapidly, and is a useful method for increasing the inherent reliability of products. However, a reliability enhancement test for torpedo products has not been fully popularized. To solve this problem, based on the characteristics of torpedo products and the technology of reliability enhancement test, the specific method of reliability enhancement test applied to torpedo products is given in this study, including the reliability enhancement test process, confirmation of test products, analysis of environmental stress and typical test profiles. The method is discovered to be logical and feasible it can serve as a reference for the reliability enhancement test of torpedo products.
