The Design of Motion Platform Controlled by Double Motors

Nowadays, motion platforms are widely used in dynamic film, motion simulation, robotics, marine, automotive simulator and other fields. These platforms require two degrees of freedom at least. This paper describes a motion platform controlled by double motors. By controlling the positive and negative going motion of the two motors, the platform can rotate freely around the two axis in the horizontal plane. These movements can simulate acceleration, deceleration, shock, bumps, rapid shake and so on. The platform is directly driven by two motors. It not only maintains the superiority of the electric system platform, but also is cheaper. This platform is a kind of dynamic device which is applied to the real experience of virtual environment, so it can be applied to the car simulation, 4D dynamic racing game, 4D dynamic film, etc.
