CAARC高层建筑标模动态测力研究

Measurement of Dynamic Forces and Moments on CAARC Standard High Building Model

CAARC高层建筑标模的动态测力试验在南京航空航天大学 NH-2低速风洞中进行。在均匀流场中以及模拟大气边界层中分别测量了模型的动态气动力和力矩的平均值、均方根值、峰值。试验目的是为检测 NH-2风洞的大气层边界模拟技术 ,动态天平、测试仪器以及动态数据采集和处理系统。试验结果表明 ,CAARC标模的所有动态气动特性在 NH-2中的测量值与国外资料中报导的结果符合得较好。因此 ,NH-2风洞的大气边界层模拟技术 ,动态天平。

The measurement of dynamic forces and moments on CAARC standard model is carried out in NH-2 low speed wind tunnel in Nanjing University of Aeronautics & Astronautics. The average root mean square and peak value of dynamic forces and moments of the model are measured in free flow field and boundary layer flow field, in order to check the technique simulation dynamic balance of boundary layer, test instruments and data acquisition and processing system. Experimental results show that the valus of forces and moments in NH-2 wind tunnel are good agreement with those in abroad references. Thus NH-2 low speed wind tunnel has ability to do test in measurement of dynamic forces for high building.
