Abstract
In the process of inflation and stabilization descent for the parachute, a coupling effect is generated between the the structure deformation and changes in the flow field around the canopy, which is significant important as well as the dynamic effect of the parachute. Besides, the peak value of the loads on the parachute often occurs in the inflation process where the canopy shape is dramatically changed. Therefore, it is necessary to study the impacting process of the parachute airbag. In this paper, the Arbitrary Lagrangian Eulerian algorithm (ALE) and fluid-structure coupling function of the explicit dynamics program LS-DYNA is used to simulate the stabilizing droplet process of the parachute. The results show that the modeling method and parameter control is feasible. On this basis, the finite element model of the parachute without parasailing is established, and then its inflatable process is simulated, obtaining the impact properties.
