The Design of the flight simulator mechanism is an essential link in the development of aviation technology. The six-degree-of-freedom Stewart parallel mechanism is used as the mechanical body of most traditional flight simulators. They can simulate the six-degree-of-freedom motion of the aircraft. However, the reachable attitude of the moving platform of the Stewart parallel mechanism is relatively small, and its range of motion is ± 35°, which can only achieve a small range of yaw, roll and pitch. It can only satisfy the simulation of the attitude change of a civil aviation aircraft. A 4PUS-PPPS redundant parallel mechanism equipped with visual function is proposed to simulate the high motion performance of fighter aircraft, which can realize the movement of angles (− 90°,178°) around the horizontal axis of the aircraft. The flight attitude data of the aircraft were acquired and processed by filtering algorithms in the software of Unity 3D environment. Then, the three steering gears that simulate the action of the moving platform are controlled by the processed data, which realizes the simulation control of the combination of virtual and honest and provides a new idea for the research of redundant parallel mechanisms.

飞行模拟器机构的设计是航空技术发展中必不可少的环节。六自由度斯图尔特并联机构被用作大多数传统飞行模拟器的机械体。他们可以模拟飞机的六自由度运动。但Stewart并联机构的动平台可达姿态较小，其运动范围为±35°，只能实现小范围的偏航、横滚和俯仰。只能满足对民航飞机姿态变化的模拟。提出了一种带有视觉功能的4PUS-PPPS冗余并联机构来模拟战斗机的高运动性能，可以实现围绕飞机水平轴的角度（-90°，178°）运动。飞行器的飞行姿态数据在Unity 3D环境软件中通过滤波算法获取和处理。然后，通过处理后的数据控制模拟移动平台动作的三个舵机，实现了虚实结合的仿真控制，为冗余并联机构的研究提供了新思路。
