具有防地震脱轨保护功能的实物转向架振动台实验

Full Scale Experimental Verification on the Function of Anti-Derailing Guard Rails to the Derailments due to Large Earthquakes

介绍了利用新干线无摇枕实物转向架模型车辆在大型振动台上模拟东海地震波进行大位移的激振试验。确认防脱轨装置对地震横向振动摇摆脱轨起到有效作用,对地震垂向振动的车辆摇摆运动、脱轨倾向和防脱轨保护的功能影响较小。

The excitation test with great displacement simulating the Tokaido earthquake wave on the large vibration test stand for the model vehicles with full scal bolsterless bogies for Shinkansen is described. It is confirmed that the derailment prevention equipment has significant effect on the swinging derailment during lateral vibration in earthquake, but has fairly small effect on the vehicle swinging motion, derailment trend and derailment prevention during vertical vibration in earthquake.
