摘要

轨道车辆碰撞试验中的加速度数据是考核车辆耐撞性的重要参考依据，由于轨道车辆质量和刚度大，碰撞时加速度波形不同于汽车碰撞测试波形，有必要对轨道车辆碰撞加速度传感器进行选型试验，通过在同一批次试验中，对比不同阻尼系数、不同量程的加速度传感器数据，得到适合轨道车辆碰撞试验的加速度传感器。试验研究表明，阻尼系数在0.4~0.8左右，量程在(1 000~2 000),g,左右的加速度传感器较适用于轨道车辆碰撞试验。

Abstract

The acceleration data in crash test of railway vehicles is an important reference for evaluating the crashworthiness of vehicles. Because of the large mass and stiffness of the rail vehicles, the acceleration waveform of railway vehicles crash test is different from that of car crash test. So it is necessary to carry out the type selection test for the crash acceleration sensor of rail vehicles. By comparing the acceleration sensor data with different damping coefficients and different ranges in the same batch of tests, an acceleration sensor suitable for the crash test of rail vehicles was obtained. The experimental results showed that the acceleration sensor with damping coefficient around 0.4-0.8 and range around 1 000,g, -2 000,g, was more suitable for the railway vehicle crash test.
