摘　　要：利用Stewart六自由度并联机构运动学反解控制算法,设计了六自由度飞行姿态仿真平台,将飞行姿态数据转化为执行机构舵机的运动控制参数。通过共享内存方法获取Prepar 3D模拟飞行软件飞行姿态数据,进而导入仿真平台进行验证,结果表明,该姿态仿真平台运动精度与稳定性较好,适用于理论验证。A six-DOF platform is designed employing the control algorithm of Stewart’s six-DOF parallel mechanism.Flight attitude data is converted into the actuator motion parameters through inverse kinematics to drive servos.The flight attitude data of Prepar 3D the simulation flight software can be obtained through shared memory and then imported into the simulation platform to conduct verification.Results show that the attitude simulation platform has high motion precision and stability and can be used for theoretical verification.
