Simulation and comparison of different dynamical models of space webs

Space webs which have great potential applications in orbit Service, recovery of spacecraft, orbit cleaning, space interceptor, woven from lightweight and pliable rope, are webs of unstable configuration formed by throwing and spreading. This paper adopts the finite element software ABAQUS in order to model the system of elastic webs and the system of flexible webs, compares the projecting of two finite element models, proposes metrics on the deployable of webs' system and focuses on traction mass, projectile point, projectile velocity of webs and equivalent damping effect of ropes on webs' deployable under a variety of different conditions. The results of simulation indicate that the unfolding effect of flexible webs is better than that of the elastic webs; traction mass, projectile velocity of webs and equivalent damping effect of ropes are the key factors in effectively webs' unfolding, and projectile point is the main factor to decide the unfolding area to the predetermined location.
