氢燃料发动机关键零部件时变可靠性设计分析

Analysis of time-dependent reliability design for key components of hydrogen fueled engines

文章针对氢燃料发动机由于燃烧机理尚不完全明确而在工作时经常受到不可预料的损伤现状,从不确定性因素和时变两个角度入手,为氢燃料发动机关键零部件的选择了可靠度计算模型,分析了氢燃料发动机关键零部件时变可靠性优化设计模型,讨论了基于盲数方法的氢燃料发动机关键零部件时变可靠性模型求解方法。

Aiming at the fact that hydrogen fuel engines are often subject to unpredictable damage due to the unclear combustion mechanism,the reliability calculation models for the key components of hydrogen fuel engines were chosen from the perspective of uncertainty and time-varying factors.And,the time-varying reliability optimization design models of the key components of hydrogen fuel engine were analyzed.And then,the methods of solving the time-varying reliability model for key components of hydrogen fuel engine based on the blind number methods were discussed.
