Application of Reliability Simulation in Torpedo Products

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.
