| Abstract: | Space webs are new species of lightweight flexible space structure, which indicate great potential application value. This paper conducts an in-depth research on the issues of the dynamic characteristics of space web. Firstly, the dynamic model of space web is established, which considering different mechanical environment in space and on ground. Then, the reliability of the simulation model is validated by the ground test. At last, based on deployment parameters, which are deployment area, flight distance, etc, the deployment characteristic of flexible web, such as the web shape, stress distribution and energy, is simulated and analyzed, and the influence of the orbit height, capture direction and casting parameter to the deployment characteristic is also considered. |
