Design And Kinematic Analysis For A Novel Flight Simulator

In order to improve the rotation angle of traditional motion simulator, this thesis use a novel flight simulator based on a kind of parallel mechanism with redundant actuation. Redundancy parallel mechanism has many benefits, such as large angle attitude, high stiffness. The main contents are as follows:Firstly, a new kind of parallel mechanism with redundant actuation as motion mechanism is performed, and then the structure, degree, assembly condition are analyzed to validate its exercise performance.Nest, the kinematics of motion mechanism is analyzed, including forward kinematic, inverse kinematic, velocity and acceleration analysis. And the input and output equations of displacement, velocity and acceleration are built for the subsequent research.Then, the performances of the flight simulator are analyzed. Work space of the translation attitude is obtained for the initial attitude. The specific numerical pose space is obtained to prove the performance of the flight simulator. By using the velocity Jacobian matrix the mathematical criterion for parallel and series singular is obtained to ensure the safe and reliable motion.After that, in order to verify performance of the flight simulator in practice a mechanical body with control system is built. Parallel mechanism control system based on multi axis motion controller is built.Last, the motion mechanism is analyzed using the physical prototype. The reliability and validity of control strategy based on virtual prototype is verified by single degree of freedom motion. The pitching and take-off movement are analyzed.The results of this research are used to verify the design and kinematic analysis.
