利用全尺寸转向架振动台试验探讨地震情况下铁道车辆的脱轨机理

Study on the Derailment Mechanism of Railway Vehicle by Earthquake Ground Motion Based on Full-Scale Bogie Experiment

介绍了利用振动试验台研究东海道新干线标准结构有碴轨道条件下,车辆在地震情况下的脱轨机理,从激振频率和激振振幅2个角度出发,分别讨论了试验结果和仿真结果,两者较为吻合,可以互相验证。

The vibration test bench is used to research on the derailment mechanism of rolling stock under earthquake with the conditions of the ballast rail of the Tokaido Shinkansen standard structure. The test result and simulation result are discussed respectively from the two aspects of excitation frequency and excitation amplitude. The two coincide fairly well and can be mutually verified.
