Abstract

The invention provides a U-shaped wind tunnel test train accelerating system which is characterized by comprising supporting frames, U-shaped slide rails, a test bridge span model, a train model, a special train hook device and a special train tripping device, wherein the supporting frames are mounted at the two ends of the test bridge span model; the supporting frames are provided with the U-shaped slide rails; the U-shaped slide rails are provided with the special train hook device and the special train tripping device; the train model is suspended on the special train hook device; and the special train tripping device is arranged at the contact part of the special train hook device and the train model. The U-shaped wind tunnel test train accelerating system provides technical guarantees to a test research on pneumatic performance of a wind-vehicle-bridge system.

Description

technical field [0001] The invention relates to a high-speed railway "wind-vehicle-bridge" wind tunnel test system, in particular to a U-shaped wind tunnel test train acceleration system. Background technique [0002] The rapid development of high-speed railway is an important manifestation of national economic development and national strength enhancement. According to the "China Railway Medium and Long-Term Development Plan", there will be many high-speed railways across my country's vast rivers, lakes, mountains and valleys, and they will surely face severe and complex wind environment tests. There have been many wind-induced train derailment and overturning accidents at home and abroad, making the safe and comfortable operation of high-speed trains in complex wind environments the focus of attention of governments at all levels and the people. Although the research on the stability of train operation under the action of cross wind has received extensive attention, it is...
