  Study on the Rocking Phenomenon of Parachute Rope

  By Tae Jin Pak, Sol Song Pak, Kwang Ho Kim, Kyong Jun Kim, Won Hak Kim

  Abstract: With the constant development of computer technology and the development of numerical simulation techniques, the simulation of the dynamics of the parachute is becoming increasingly accurate. To eliminate the effects of large deformation of the grid in the conventional parachute simulation, we chose the parachute model using the smooth particle hydrodynamics method and performed a steady-state fluid-solid coupling numerical simulation, which is in good agreement with the calculated gas power …

  Fluid-Structure Interaction Simulation of Parachute by Eulerian-Lagrangian penalty method

  By Pak Sol Song, Hyong Gyu Jon, Kum Kwon Choe, Kwang Ho Kim, Jong Dok Ri

  Abstract: In general, modeling and simulation of a model consisting of fluid and solid combinations has been considered difficult, and it has become impossible in terms of computer dependencies and accuracy to be analyzed by Fluent or other programs. The parachute evaluation process, which is historically based on a large amount of experimental data, necessitates many falling experiments. These tests can be costly and time-consuming, and they don't always allow for …
