摘　　要：A position and orientation compensation mechanism for the automatic docking device of a launch rocketwas established.The docking process was simulated,and the maximum docking deviation was used for the prototype testing of the compensation mechanism.The compensation mechanism mainly comprises four column pairmotion branch chains with the same structure.When the position of the ground connector panel changes relative to the moving platform,the sliding rods in the four motion branch chains move and rotate to either compress or stretch the connected spring,thereby compensating the position and orientation.First,the dynamic simulation model of the compensation mechanism was established.The docking process was then simulated under the maximum docking deviation.Bench testing of the automatic docking device prototype was carried out.Afterwards,the device was manufactured,and a maximum load test and maximum deviation test were carried out.The results demonstrate that the compensation mechanism meets the design requirements,and the spring stiffness was found as the most important factor in determining the mechanical properties of the system.The proposed compensation mechanism has a number of advantages,including a simple structure,large load bearing capacity,small size,simple installation,and adjustment. 关键词：PRIMING connector position and ORIENTATION compensation mechanism spring dynamic simulation PROTOTYPE test
