- Abstract
The parachute opening process in low-speed airflow is simulated based on ALE method. The numerical results of the structural stress, the velocity vector, the pressure contour of flow field, the diameter change of canopy and so on are obtained. Compared with the test, the opening processes are the same, and the phenomenas of top sink and canopy shake are observed. Finally, the mechanical mechanism explanation of canopy shake and the huge noise caused by canopy flapping in tests, and the prediction of dangerous section during opening are given by the analysis based on numerical results.
