Mechanical Properties of Wind Tunnel Testing Support Device for Parachute

以某火星降落伞在2.4m×2.4m跨声速风洞的空气动力试验为背景,设计了其风洞试验的结构支撑装置,并对其进行了力学建模,得到了支持装置的数学模型,根据得到的数学模型对重力影响特性、结构静力学特性和动力学特性进行了仿真分析。结果表明设计的某火星降落伞2.4m跨声速风洞试验支撑装置具有较好的强度特性和刚度特性,满足试验要求。

The 2.4m×2.4m transonic wind tunnel test for a parachute for Mars probe is investigated in this paper.The structural support device for the wind tunneltest is designed and its mechanical model is established.According to the influence of the gained mathematical model on the gravity and the static and dynamic property,the simulation analysis is done.The results indicate that the designed Mars probe parachute has better strength and larger stiffness.This design meets the requirements of the wind tunnel testing.
