Dynamic Analysis of the Stewart Platform for the Motion System of a Driving Simulator
Driving simulators are systems able to produce a virtual driving environment, resembling real driving conditions, in order to increase the comfort and safety of future cars. The required motion trajectory of the driving simulator can be generated with a parallel robot (Stewart platform), capable of moving with 6 degree of freedom. The paper presents the main physical parameters of the components (synchronous motor, screw-ball mechanism) and a multiphysical dynamic analysis of the Stewart platform in order to evaluate the movements which have to be simulated by the motion system of a driving simulator. The developed model is confirming that the six synchronous motors with permanent magnet, which are actuating the moving platform through belt drive and screw-ball mechanisms, are able to precisely place in location and orientation the motion platform and are providing the required accelerations.
