In our previous study, a torsional model was used to perform a dynamic analysis of a wind turbine drivetrain. However, detailed characteristics could not be obtained with this torsional model. In this paper, the mathematical model of the wind turbine drivetrain is extended to a three-dimensional dynamic model. A typical arrangement with one low-speed planetary gear stage and two highspeed spur gear stages is used in this work The governing equation of the drivetrain is derived by using Lagrange%26apos;s equation. Lagrange%26apos;s equation takes into account the kinetic energy of each component and potential energies from the shaft, bearing, and gear mesh. The governing equation is solved numerically using direct numerical integration. A dynamic analysis is carried out to investigate the transient response of the drivetrain system.
