摘要
由于发动机叶片在工作中存在诸多参数的不确定性 ,而这些不确定因素包含结构元件弹性模量、结构强度和外载荷等服从统计规律可作为随机变量处理 ,因此通过建立叶片的力学模型 。
Considering the uncertainty of influencing parameter in engine blade operation ,including module?strength of structural members,and loads applied which are assumed to be subjected to the statistical law and be random variables,the reliabilityof engine blade is obtained by creating its mechanical model and combining Stochastic Finite Element Method(SFEM)with the geom.etrical optimization method.It is viable.
