ABSTRACT
The inverse dynamics method is applied to the investigation of dynamical behavior of a
parallel manipulator. The substructure technique is used for creating a differential-algebraic
system of equations that describes motion of the Stewart-Gough platform. The system of
equations is modified into a set of linear differential equations for the determination of
the solution of the inverse dynamics problem. A computational algorithm is developed to
solve the inverse dynamics of the manipulator. Several trajectories of the moving platform
are simulated as a result of the inverse dynamics problem of the Stewart-Gough platform
according to the substructure technique.
