A design software tool for conceptual design of wind turbine gearboxes

The paper reports the development of a design software tool for wind turbine gearboxes. It facilitates the conceptual design of wind turbine gearboxes supporting designs with different combinations of epicyclic and parallel gear stages. Analyses of gear bending strength and pitting resistance are in accordance with the AGMA2001 standard. The calculations of the AGMA geometry factors and are verified in accordance with the AGMA 908 information sheets. A case study of a 2MW and three phase asynchronous generator with a nominal rotational speed around 1600 rpm has been tested to demonstrate the capabilities of the design software tool.
