Research And Implementation Of The Three Degrees Of Freedom Motion Platform

The three degrees of freedom platform has been applied to the driving simulator more extensive, Since it can provide the main dynamic driving simulator effects, additionally it has less joint actuated and higher capability but lower cost. In this paper, three degrees of freedom motion platform has been studied and realized based on a certain type of driving simulator performance requirements.First, in the paper, a kind of the three DOF motion platform with anti-torque arm has been identified based on the theory of space motion agencies. Secondly, the key factors, such as the range of the platform, the stroke length of electric cylinders, the sizes of panels etc., as constraint conditions was concluded, the optimal weighed value of the controllability and the structure size of the platform as the optimal objective functions were chosen, the algorithm parameters of the platform mechanism were optimized based on acceleration genetic algorithm, and the optimization results were applied to the design of a kind of the three DOF motion platform with anti-torque arm. Thirdly, All-digital servo control scheme has been proposed for the design of the drive control system, and it has been Improved anti-jamming capability of the control system. Fourthly, The power matching for the drive control system has been determined based on the dynamic simulation of the Space motion mechanism. Finally, The internet applications have been developed ground on Wince6.0 and the process of designing the real-time control system for the platform has been carried out. The results have showed that all performances have meet the design requirements. The three-DOF motion platform system which has been Studied and implemented in this paper has been put into use, and small batch production.
