开伞高度对救生伞开伞动载与附加质量的影响研究
Research on the Impact of Opening Height on Parachute Dynamic Load and Added Mass of Rescue Umbrellas
摘要
Abstract
A large number of airdrop experimental data from both domestic and international sources indicate that the opening dynamic load of compact fabric circular parachutes,such as the eight-panel canopy parachute and C-9 parachute,is closely related to the opening altitude.Currently,methods for studying the parachute opening process through fluid-structure interaction(FSI)are quite common.However,research on the influence of opening altitude on the opening dynamic load is not very deep.This paper conducts a numerical simulation of the opening process of the C-9 parachute using the Arbitrary Lagrangian-Eulerian(ALE)method,and compares the simulated opening dynamic load with experimental data to verify the reliability of the simulation method.Furthermore,by studying the opening process of the eight-panel canopy parachute at different altitudes,the paper analyzes the opening dynamic load and added mass,clarifying the mechanism of how opening altitude affects the opening dynamic load and whether the added mass has a significant impact on the dynamic load.The conclusions from the simulation show that as the opening altitude increases,the opening dynamic load increases while the added mass decreases,providing theoretical support for the design of load limits for parachutes at different altitudes.关键词
