Abstract

A wind tunnel testing system for annular rail models, vehicle models and bridge models includes a wind tunnel model test box (1) provided with at least one opening, wherein the space between opposite vertical side walls in one group on the wind tunnel model test box (1) is a wind tunnel testing zone; two opposite holes (18) are formed in the opposite vertical side walls in one group; a bridge model (5) is arranged between the two opposite holes (18); a rail is arranged on the bridge model (5); a vehicle model (4) for test is movably connected onto a rail (2); the rail (2) includes a guiding section rail (2) and a testing section rail (3); the guiding section rail (2) and the testing section rail (3) are connected from end to end to form an annular rail provided with an annular loop; the annular rail penetrates the two holes (18) simultaneously, or the annular rail simultaneously passes by the two holes (18) and the outer part of the wind tunnel model test box (1). According to the invention, the vehicle model can run on the rail in a cyclic manner, and the testing data obtained through testing more conforms to the actual condition.

Description

technical field [0001] The invention relates to the technical field of testing the aerodynamic characteristics of mobile trains, in particular to a wind tunnel test system for ring track, vehicle and bridge models. Background technique [0002] When high-speed railways cross special terrains such as rivers, lakes, mountains and canyons, they will inevitably face severe strong crosswinds. There have been too many train derailment accidents caused by strong crosswinds at home and abroad, so that the stability of train operation under strong crosswinds has received extensive attention. In order to ensure the safe operation of vehicles under strong crosswind, it is necessary to study the aerodynamic state of vehicles and bridges. The vehicle models in the existing vehicle model wind tunnel test devices are all static. The test system first only conducts coupling tests on the bridge or a single object of the stationary vehicle, without considering the mutual aerodynamic effect b...
