Abstract
The new type of three jaw docking mechanism is designed for use in orbiting spacecraft, the mathematical model is given and its working characteristics are analyzed. By establishing the mathematical model of the interaction of the parts under the different coordinate system, it is obtained that the corresponding kinematic characteristics; contact collision dynamics model is established by using the Hertz model theory, dynamic equation is established by Newton-Euler method, and simulation analysis are carried out by using the dynamics simulation software ADAMS, through the simulation analysis of three groups with different initial conditions, the results show that it achieve reliable grasp with good performance, it provides the lock claw curve in contact collision force and movement characteristics curve. These curves provide reference to improve the performance of docking mechanism.
