Towards Washout Filter Concepts for Motion Simulators on the Base of a Stewart Platform
Sprache des Titels:
Special Issue: 82nd Annual Meeting of the International Association of Applied Mathematics and Mechanics (GAMM)
In this paper we present a pneumatically driven Stewart platform as a basis for motion simulators. Motion platforms, that simulate perceived situations in aeroplanes, cars or ships, have workspace constraints in every degree of freedom. Therefore it is necessary to adapt the accelerations and angular rates in order to stay within the physical restrictions. For realizing a flight or ride simulator on the basis of the Stewart platform, "Washout Filters" are used to change the signals
of the open source software FlightGear and to minimize the sensation error between simulator and aircraft. Different filter concepts are implemented and evaluated. The platform presented in this document is a parallel kinematic robot, driven by fluidic muscles. The pneumatically actuated muscles are only able to produce tensile forces. Therefore a spiral spring from a passenger car is used to apply the compressive
forces and torques.
