This paper describes a design method of deployment locking mechanism for backward docking communication antenna of space station core module. Firstly, the implementation process of communication antenna deployment locking mechanism is introduced. Secondly, the deployment driving torque of the mechanism is determined through mechanism dynamics simulation and actual measurement of the maximum resistance torque of high-frequency cable in the deployment process. According to the product design and construction specifications of the space station, the margin value of driving torque is checked to meet the design requirement of the space station. Finally, through mechanism dynamics simulation, the impact load in place is analyzed. While ensuring the deployment time and driving margin, the mechanism design is optimized to make the deployment process stable and reliable.
