Mechanism Design And Simulation Research For Space Spinning Web System

Considering the space debris environment in recent years, the processing of on-orbit debris will become the important problem of the space station construction in the third stage of China’s space manned flight. For the non-cooperative targets such as the space debris, the space web capture system, a new flexible capture technology, has been proposed, but the winding and uncontrolled shape of space web will happen during the web deployment of existing caputre system. Around these problems, a new spinning space web system by the centrifugal force is put forward and the corresponding researches will be conducted:Firstly, based on the capture mission and design requirements, the structure and mechanism schemes of the spinning web system are designed, and the three-dimensional model of the whole system is established. In addition, the material, configuration, deployment strategy of space web are also analysed. Secondly, for the winding and uncontrolled shape of space web, the three-dimensional mathematical analytical model and kinematic model are established to simulate the deployment of spinning web by using MATLAB and ADAMS software respectively. The results show that the spinning web can deploy steadily and orderly in short time and keep the stable shape after the deployment. Afterwards, for the collision problem between the web and target, the flexible and rigid bodies are rapidly modeled by the APDL parametric language in ANSYS/LS-DYNA software, which can effectively show the collision effect and the flexibility of the spinning web. Finally, the simple ground test scheme of spinning webs is proposed to provide the certain reference for the ground test in the future.
