舰船动力装置可靠性研究

Study on the Reliability of Ship Power Equipment

科学、准确和高效地评估船舶装备在特定的时间和条件下的任务成功性水平,是舰船装备综合保障的一项重要的基础性工作,正确的评估模型又是准确、科学评估的依据和基础.首先叙述研究舰船装备可靠性的目的和背景,再以蒸汽动力装置为例建立动力装置的可靠性评估模型.通过可靠性评估模型,根据单元的RMS参数和不同的舰船任务要求,可以计算得到舰船所能完成各阶段任务的概率和所处状态的概率,为舰船保障提供依据.

Evaluating the mission successful level of ship equipment rationally, accurately and efficiently under the particular time and condition is an important foundation work of ship equipment comprehensive guarantee.The right valuation model is also the basis and foundation for evaluating accurately and rationally.Firstly, it describes the purpose, background of researching ship equipment reliability.Secondly, it takes the steam power equipment for example to build up the reliability valuation model of motive device.With the reliability valuation model, according to the RMS parameters of unit and different ship task requests, it could compute to get the rate that ships complete task of each stage and the rate of status, which is useful for ship safeguard.
