Wind tunnel experiment scale model supporting rack

Abstract

The invention discloses a wind tunnel experiment scale model supporting rack. The supporting rack comprises a fixed platform, an adjusting turntable, a driving component and an experiment table, wherein the fixed platform is suitable for being fixed to the ground and provided with a groove structure, and a turntable connecting base is arranged in the groove structure; the adjusting turntable is arranged on the turntable connecting base and located in the groove structure; the driving component is connected with the adjusting turntable and used for driving the adjusting turntable to rotate around the rotation axis of the adjusting turntable; the experiment table is arranged on the fixed platform. According to the wind tunnel experiment scale model supporting rack, the driving component is arranged to drive the adjusting turntable to rotate around the rotation axis of the adjusting turntable, so that on one hand, manual adjustment of the angle of the adjusting turntable is omitted, and operation by production workers is facilitated; on the other hand, the requirements for wind tunnel experiments of automobiles with different scale models under different working conditions are met.

Description

technical field [0001] The invention relates to the field of transportation equipment test research, in particular to a wind tunnel test scaled model support platform. Background technique [0002] The automobile wind tunnel is a kind of test equipment for automobile aerodynamics research. When the vehicle wind tunnel is used for scaled model experiments, on the one hand, the balance has a large range and low precision, and the supporting platform has a great influence on the air flow field around the car model; on the other hand, the traditional supporting platform has limited functions, and the experiment In the process, it is necessary to manually adjust the yaw angle of the model, which not only cannot meet the experimental requirements of various working conditions, but also has a large workload and is inconvenient to operate. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least...
