| Abstract: |
| Space web system is a new type of lightweight flexible space structure, which indicates great potential application value. Firstly, according to different mechanical environment in space and on the ground, the dynamic model of space web was established. Then, the reliability of the simulation model was validated by the ground test. Finally, based on performance parameters, for instance, deployment area, flight distance, etc, the dynamic characteristics were simulated and analyzed, such as the web shape, stress distribution and energy change, and the influence of the orbit height, capture direction and casting parameters on the deployment process were also analyzed. |
