Abstract

The invention relates to a vehicle-rail-bridge shaking table test device with a circular rail. The vehicle-rail-bridge shaking table test device comprises a vehicle model (3) used for simulating a high-speed rail train, a circulatory rail used for providing a circulatory running track for the vehicle model (3), a shaking table (4) used for simulating bridge earthquake states from the bottom of a bridge model (4), a guide section rail support (6) used for supporting the end of the circulatory rail from the bottom, and a test data acquiring device (12). An anti-loosening mechanism used for preventing the vehicle model (3) from falling off the circulatory rail is arranged between the vehicle model (3) and the circulatory rail.

Description

technical field [0001] The invention relates to high-speed railway vibration test equipment, in particular to a vehicle-track-bridge vibration table test device with a circular track. Background technique [0002] Although my country's railway industry started late, it has developed rapidly, and now it ranks among the top in the world in terms of total mileage and operating speed. Due to my country's vast territory and complex geological conditions, railways inevitably cross many harsh geographical areas such as mountains, valleys, rivers and lakes, so bridges account for a large proportion of railway lines, especially in recent years for high-speed railway lines. In order to meet the requirements of track smoothness and stability, high-speed railways often use viaducts for several kilometers or even more than ten kilometers, which makes it very likely that trains will be on the bridge when an earthquake occurs. Train derailment or overturning accidents under earthquakes oc...
