High-speed train dynamic model test platform

Abstract

The invention discloses a high-speed train dynamic model test platform, and belongs to the technical field of high-speed train aerodynamic performance simulation tests. According to the invention, test data can be accurately acquired under the condition of an ultra-high speed of more than 600km / h, and damage to a model train and an internal sensor in the test process is avoided, so that a pneumatic test can be repeatedly carried out. The high-speed train dynamic model test platform comprises a high-pressure air storage tank which is communicated with an upper layer pipeline; a power vehicle and a model train are sequentially arranged along the communication part; a rail bottom plate with a groove is arranged below the upper layer pipeline; a lower layer pipeline is arranged below the railbottom plate, a motor vehicle braking device is arranged in the upper layer pipeline, a transmission vehicle and a supporting vehicle which support the model train to suspend the model train are arranged in the lower layer pipeline, a transmission vehicle braking device is arranged at the tail end of the lower layer pipeline, and an ejector rod extending out of the bottom of the motor vehicle is in contact with the tail end of the transmission vehicle.

Description

technical field [0001] The invention belongs to the technical field of high-speed train aerodynamic performance simulation test, and in particular relates to a high-speed train dynamic model test platform. Background technique [0002] In the document with application number CN200910077594.5, the disclosed high-speed train dynamic model test system includes a train dynamic model unit and an air cannon drive unit.
