摘　　要：以飞机机翼调姿对接运动仿真为研究内容,通过CATIA建立运动仿真模型。利用五次多项式对机翼调姿对接轨迹进行规划,将对接过程划分为3个阶段。根据刚体位姿描述方法,用MATLAB逆解出定位器驱动量,并将结果导入运动仿真模块,完成调姿对接过程中机翼速度和加速度的运动仿真分析。仿真结果表明,机翼运动速度、加速度曲线光滑连续,调姿对接规划满足运动学要求。The motion simulation of aircraft wing adjustment-docking is studied,and the models of the motion simulation are built by CATIA.The quintic polynomial is used to plan the trajectory of aircraft wing adjustment-docking and divide the process into three steps.According to the description method of rigid body position and orientation,the inverse results of the position driver is got by MATLAB,and the results are inputted into the motion simulation module to accomplish the analysis of velocity and acceleration in the process of aircraft wing adjustment-docking.Simulation results show that the curves of the velocity and acceleration are smooth and continuous,the adjustment-docking meets the kinematic requirements.
