Abstract
En 中文
With the implementation of major aerospace projects such as China’s manned spaceflight and deep space exploration, the demand for space-based platforms such as space stations and on-orbit service platforms has become increasingly urgent. On-orbit service is of great significance for extending the lifespan of spacecraft and reducing mission costs. To this end, this paper proposes an interface layout strategy for satellites of different scales, as well as a docking mechanism design scheme centered on a lead screw claw. Firstly, based on design indicators and interface requirements, the interface layout design and analysis are completed, and the Denavit-Hartenberg (D-H) coordinate transformation method is used for simulation verification of the guided interface layout. Through multi-scheme comparison, the lead screw claw docking mechanism is selected, and the key component selection and design parameters are determined. Then, ANSYS is used to perform mechanical characteristic analysis of the locked state, including prestress modal analysis, sine and random vibration analysis, to examine the frequency response characteristics of the mechanism during launch and on-orbit phases. Finally, on this basis, a modular interface docking prototype is developed, and performance and functional tests are carried out. The test results show that all performance indicators of the developed docking mechanism meet the design requirements, verifying the correctness of the interface layout strategy and the theoretical analysis model of the docking mechanism.
