Abstract

The invention discloses a device and a method for determining the structure wind resistance test zero wind attack angle by using vehicle driving wind. The device comprises a van, a container, a wind vane component, an angular dial, a laser device and a camera. The container is arranged in the packing case of the van. The wind vane component and the camera are arranged on the container. The wind vane component comprises a wind vane front wing and a wind vane rear wing. A bearing is connected in the middle part of the wind vane component. The bearing is arranged on the angular dial through a bracket. The laser device is arranged on the wind vane, and the light emitting direction of the laser device is downwardly projected to the angular dial. The camera is used for photographing the positionof the laser on the angular dial. The device and the method can be used for the structure wind resistance test, and particularly the wind field is generated by using vehicle driving and then calibration of zero wind attack angle is performed on the structural component.

Description

technical field [0001] The invention relates to the field of experimental equipment, in particular to a device and method for determining the zero-degree wind attack angle of a structure wind resistance test by using the driving wind of a vehicle. Background technique [0002] The wind tunnel test in fluid mechanics is based on the principle of relativity of motion, fixing the physical object or physical model in an artificial environment, man-made air flow, obtaining test data, studying the gas flow and its interaction with the model, in order to understand the actual An aerodynamic experimental method of the aerodynamic properties of an object. Contents of the invention [0003] In order to solve the problem that there are few calibration methods for zero-degree wind attack angle in wind tunnel tests at home and abroad, the present invention provides a method for determining the zero-degree wind attack angle of structural components under research work. The invention ca...
