Abstract
This paper proposed a design procedure for one of these subsystems, which is the Wind
Turbine Drive Train (WTDT). The design of the WTDT is based on the load assumptions
and can be considered as the most important component for increasing the efficiency of
energy generation. In industry, these loads are supplemented by expert assumptions and
are extrapolated by static manipulations to calculate local load for the design of transmission
elements, e.g. gears, bearings, and shafts. In contrary, in this work, the multibody
system (MBS) approach is used to estimate the static as well as dynamic loads based on
the Lagrange multipliers. Lagrange multipliers are numerical parameters associated with
the holonomic and non-holonomic constraints assigned for the drivetrain model. The
computational manipulations of kinematic stabilization, mapping the generalized forces
into Cartesian respective, and implementation of velocity-based constrains into quadratic
terms are carried out and the corresponding sub-routines are constructed.
