摘要

根据多结点开伞模型建立了锥形降落伞系统的变形动力学方程组来对充气过程中的伞衣柔性体变形过程进行模拟.结合多结点模型动力学方程结算代码和计算流体力学软件

对降落伞的充气过程进行流固耦合动态仿真

从而得到充气过程中伞衣外形和流场的变化

以及充气时间、下降速度变化和下降距离等相关数据

与国外研究成果相吻合.

Abstract

According to a multi-node model

this paper has constructed dynamics equations of conical parachute system to simulate distortion process of the flexible canopy in the opening process.By combination of dynamics equations code and computational fluid dynamics(CFD) software

the fluid-structure interaction study of the parachute was carried out

and the change of its shape and flow flied

inflation time

the rate of decline

the distant of decline

and other relevant data were achieved in agreement with foreign research results.
