风电传动系统关键零部件的制造变量对其失效的影响机理研究进展

In this paper, The failures of drivetrain components exert a crucial influence on the reliability of large scale wind turbines. Recent research advances on the features of component structural failure and its mechanism are presented firstly. The impact of those component's design/manufacturing parameters on their failure processes is discussed in depth. Furthermore, some predominant study methods on the mechanical component reliability under co-existing multiple failures are provided. On the basis of above works, the challenges and difficulties in this research are concluded and analyzed, and finally, the future development trends are also predicted.
