Abstract

Provided is a three-dimensional wind pressure tester which comprises a bottom disc, a top-surface bearing thin plate, a side-surface bearing thin plate, single-arm mechanics sensors, a sealed cavity, and a single chip microcomputer. The single-arm mechanics sensors are fixed on the bottom disc through a first connecting seat or second connecting seat. The bottom disc, the top-surface bearing thin plate, and the side-surface bearing thin plate respectively correspond to a single-arm mechanics sensor. Connecting blocks are fixed on the single-arm mechanics sensors. The bottom disc, the top-surface bearing thin plate, and the side-surface bearing thin plate are fixed on a corresponding connecting block, respectively. The sealed cavity is installed inside the housing and communicated with external atmosphere through a conduit. A differential pressure sensor is installed on the conduit inserted into the sealed cavity. The single-arm mechanics sensors and the differential pressure sensor are connected with a circuit board. The three-dimensional wind pressure tester has beneficial effects of resolving the distortion and the limitation of a conventional wind pressure testing method under a strong breeze weather condition, and achieving advantages of high testing precision, good stability, simple structure, light weight, easy installation, good portableness, and a networking capability.

Description

technical field [0001] The invention relates to a three-dimensional wind pressure tester. Background technique [0002] Existing wind tunnel tests of building structure models often require the use of relatively large scale models. However, due to the limitation of the cross-sectional area of ​​the wind tunnel and the wind speed, the Reynolds model law in the boundary layer of the wind tunnel is not satisfied, which affects whether the wind tunnel test of the building structure model It can truly and accurately reflect the wind load of the actual building structure. The prototype measurement of wind pressure on the building surface is an extremely important way to solve this problem, and it provides a benchmark and verification for the existing wind tunnel test simulation methods and methods. The existing wind pressure measurement method is to open holes on the surface of the building structure, design the pipeline system, and use the micro-differential pressure sensor to c...
