Other AbstractThis paper discussed in detail the relation between the inflation impact load bearing capability and the structural sensitive parameter. Starting from solving tight-coupling characteristics of inflation impact load,and using the computational modeling and numerical simulation method, the model of coupling analysis between the structure and impact airflow was built. By adjusting structural parameters, the response of the canopy structure was analyzed and compared. The simulation result shows that the weak parts of ring slot parachute include the vicinity of radial reinforcing bands,the connection between the canopy and rope and the neighboring region of the top hole. Strengthening measures and the relation between structural sensitive parameters and load bearing capability were discussed accordingly. Research in the paper proves the validity of the simulation method for structural design. Conclusions provide the solid basis for the optimization design.
