random fatigue meaning in Chinese

随机疲劳

A time - variant reliability formulation is presented in this paper to account for the effects of fatigue , corrosion and maintenance actions on the first yield reliability of midship section modulus . a probabilistic model for long - term distribution of wave - induced fatigue stress range is established . for the purpose of obtaining the performance of structure that stands random fatigue load , the concept of stress parameter and equivalent stress range are introduced
船舶在由波浪弯矩引起的交变应力作用下，船体构件焊接点处的微小裂纹逐渐扩展；同时，随着船龄的增加，众多结构构件遭受腐蚀的作用；从而使船体梁剖面模数减小，船体梁承载能力衰减，船舶结构的安全性将受到相当大的影响。
The random analysis of structure under fatigue loading , the statistic finite element method ( sfem ) for fatigue reliability , random fatigue damage accumulation theory and fatigue reliability of structure system were studied in this paper with regard to the metal structure of engineering machine
