Chapter 4: Drivetrain Analysis for Reliable Design

Yi Guo, Zhiwei Zhang, Christopher Baker

Research output: Chapter in Book/Report/Conference proceedingChapter


This chapter described common design practices for the wind-turbine gearboxes and main bearings, along with modelling and simulation techniques employed to support and evaluate the development process. These design criteria and requirements are based on several major failure modes for gears and bearings. However, not all of the failure modes are understood well enough to be included in the design standards primarily because of the complexity of the modelling and loading conditions. Drivetrain modelling for design was discussed, and most of the modelling tools used in design are static in nature.
