Inverse Dynamics of Stewart – Gough Platform Aiming the Application at Flight Simulators

Forecasting the forces of the linear actuators with the aim of designating proportionate motors and or structural design of the motion system in flight simulators is of the considerable importance. In this paper, inverse dynamic analysis of the 6 degrees of freedom Stewart – Gough motion system, using Newton - Euler formulation approach consisting linear actuator components and moving platform dynamics with application prospects to flight simulators is illustrated. The developed inverse dynamics simulation software of the motion system is provided by the output results of the general nonlinear inverse kinematical based motion cueing system for computing the static and dynamic actuating forces in typical surge – pitch maneuver. Compared simulation results clearly indicate a significant disproportionate difference between the static and dynamic loads for the prototypical maneuver. Thereupon true attention on predicting the dynamic forces associated with the proposed inverse kinematics in structural design and or designating linear actuator is emphasized.
