Simulation Analysis And Control Implementation For A Dynamic Racing Motion Simulator

As an important direction of the development of game industry, dynamic game is supported by dynamic simulation devices – the motion simulator, which could realize the function of motion simulation. The most significant features of dynamic game are high authenticity and strong interaction. In comparison with traditional games, the entertainment experience is enhanced to a higher grade in dynamic game, which is full of fun and excitement; at the technical level, significant technological progress is found in the dynamic simulation devices compared with the traditional entertainment devices. Based on a motion simulator of the dynamic racing game with three degrees of freedom, the design of control algorithm for motion simulators with multiple degrees of freedom, kinematic and dynamic simulation and analysis of the virtual prototype model, USB communication technique between the game software(Master computer) and controller(Slave computer) are studied deeply and systematically in this dissertation.(1) The dynamic simulation model of the car racing simulator is established in ADAMS environment, the kinematic and dynamic analysis of the virtual prototype of the simulator is conducted, and the theoretical and simulation results are compared, general movement laws of the simulator and influence level of each degree of freedom on the ride comfort of the car are obtained. Parametric modeling method is applied to optimize the structure of the virtual prototype of car, and the relationship between the screw stroke and the driving force of the slider is obtained through the iterative computation of ADAMS. Considering the structure size and driving ability, the optimal solution of the screw stroke of each degree of freedom is given.(2) Based on the STM32 controller, the hardware of the pitch, yaw and roll degrees of freedom of the dynamic car racing simulator is designed, the corresponding hardware parameters are selected, the hardware resources of the control system are allocated. Based on the classical PID algorithm, the overall framework of the control system of motion simulator of the dynamic racing game is established, corresponding tuning rules and methods are given; Based on the racing game software developed under Unit 3D, control experiments with load are conducted on the motion simulator, good performance of this system is demonstrated by experiment results. USB data transmission and communication technology is studied, the recognition method between host computer and slave computer is proposed, and related data transfer protocol is established.(3) Based on the rFactor car racing software and frame of the control system mentioned above, a motion simulator control system for the rFactor racing game software is established, simultaneous control experiments for the rFactor car racing game software with the pitch and roll degrees of freedom of the motion simulator are conducted, the synchronization and coordination of the rFactor racing game software and the movement of the motion simulator are realized, a complete dynamic game products is developed.
