Design of Docking and Locking Mechanism for Extravehicular Vacuum Environment

According to the demand of the space station experiment cabin extravehicular expose payload and the mechanical arm snatch ability,we design the docking and locking mechanism which transfers the resource of space station to the expose payload.To suit the vacuum,high and low temperature alternating,irradiative environment we have finished special designing.To suit the dynamic environment during the launch phase we have finished dynamics simulating and calculating,besides that a series of experiments approves that the designing satisfies the demand of using.
