Device for testing structure three-component coefficient through automobile driving wind and method thereof

一种利用汽车行驶风测试结构三分力系数的装置及方法

Abstract

本发明的目的是提供一种用于研究风作用下结构构件三分力系数的装置和方法,具体的说是一种通过车辆运动产生风场,进而结构构件三分力进行测试研究的移动式类风洞装置。本发明中的装置包括运输车辆和装载在车辆货箱上的设备柜;所述的设备柜上设有试验平台,所述的试验平台上设有用于调整风攻角的圆形转盘;所述的圆形转盘上设有用于固定测力天平和结构构件模型的支架。本发明装置简单操作便利,能利用真实的环境状况,试验花费低廉,可成为风洞试验之外有益的补充方法,并可广泛适用于各种结构三分力系数的测定。
The objective of the invention is to provide a device for searching a structural element three-component coefficient under the wind effect and a method thereof, and particularly provides a mobile quasi wind tunnel device for testing and researching three components of the structural element through a wind field generated by vehicle movement. The device comprises a transport vehicle and an equipment cabinet which is loaded on a vehicle trunk. The equipment cabinet is provided with a test platform. The test platform is provided with a circular rotating disc used for adjusting a wind attack angle. The circular rotating disc is provided with a support which is used for fixing a force measuring balance and a structural element module. The device is simple and convenient to operate and low in test cost and can use the real environmental conditions so that the device and the method can be a beneficial supplementary method apart from the wind tunnel test and can be widely applied to determination of the three-component coefficient of various structures.
