可靠性仿真在鱼雷产品上的应用

Application of Reliability Simulation in Torpedo Products

针对传统可靠性试验耗时长、成本高的问题,给出了可靠性仿真的基本内容和工作流程,针对鱼雷产品中的典型电子组件开展可靠性仿真建模、热应力和振动应力仿真分析、故障预计和可靠性评估,以得到产品设计薄弱环节、潜在故障信息和平均首发故障时间等。分析结果表明,可靠性仿真能够确保在鱼雷产品设计早期消除故障源,从而提高鱼雷产品的鲁棒性和故障预测能力。

The traditional reliability test is time-consuming and requires high cost.Therefore,this article provided the basic content and workflow of reliability simulation and conducted reliability simulation modeling,thermal stress simulation analysis,vibration stress simulation analysis,fault prediction,and reliability evaluation for typical electronic components in a certain torpedo product,so as to obtain weak links in product design,potential fault information,and average first failure time.The analysis results show that the reliability simulation can ensure the elimination of fault sources in the early stage of torpedo product design and thus improve torpedo product robustness and fault prediction ability.
