Description
Summary:Flight simulator is a ground simulator for training pilots. It can vividly reproduce the flight status of aircraft in real environment. It has the advantages of high accuracy, large carrying capacity, safety and reliability, and flexiblility Flight simulator usually uses SixDOF (six degree of freedom, SixDOF)Stewart platform, and its motion characteristics are the key indicators affecting its performance Firstly, the parameterized model of the SixDOF Stewart platform is established, its trajectory is designed and tested, and various structural parameters are analyzed and the basic dimensions of the platform are determined; secondly, a complete threedimensional model is established according to the structural parameters, and its spatial motion state is analyzed; finally, the kinematics and dynamics simulation analysis is carried out and the overall performance is studied The trajectory points of the six legs are basically coincident with the fitting curve of the quintic polynomial, and the movement of the six legs is in accordance with the quintic polynomial law, which ensures that the speed and acceleration do not have large mutations, thus ensuring the stability of the upper moving platform.
