基于DBN的小型无人船舶动力系统可靠性分析
Reliability Analysis of Small Unmanned Ship Power System Based on DBN
摘要
Abstract
The reliability of the power system is particularly important for unmanned ships.This study aims to design the pow-er system of small unmanned ships.Considering the logical structure,redundant configuration and dynamic behavior of the system,the dynamic fault tree is mapped to the dynamic Bayesian network,and the reliability modeling and analysis method of complex sys-tems based on the dynamic Bayesian network is proposed.The reliability of the overall power system of the three operating modes are analyzed,the optimal operating mode and the key important components are selected,and the redundancy of the key important com-ponents is re-configured.The results show that the hybrid operation mode is the best choice,and the AC/DC converter is the most important component.After redundant configuration,the overall reliability can be improved significantly.This study can provide ref-erence for the reliability design and optimization of unmanned ship power system.关键词
