In order to provide a new way for dynamic simulation experiments, a real-time solution for the six degree of freedom platform was developed. The mathematical model of an improved Six-DOF Stewart platform was used to study positive solutions and inverse solutions. According to the parameters of different platforms, different function signals were selected to generate motion control data by using Visual C++ programming. Motion control card was embedded into industrial computer, data was sent automatically to the control card by the program when the platform ran. The output of the control card was analog voltage, and it was amplified to send to the proportional valve, then the flows of six hydraulic cylinders were controlled by the six proportional valves. So a closed-loop control CNC system was formed. The expected action could be realized by the platform. Experiments have proved that the method is simple, efficient and easy to operate. It can not only accompany the implementation moving of relevant actions in the 3D movie theater, but also provide the signal source for the road spectrum of simulated driving test of the automobile
