摘要
本文分析了移动周期荷载作用下轨道结构的动力特性,通过计算得到的轨道位移响应解释了高速铁路中的轨道位移波现象。此外,还分析了轨道阻尼对高速铁路轨道结构动力特性的影响。计算结果表明,增大轨道阻尼可以抑制轨道位移波的产生,提高临界速度。
In this paper, the dynamics property of high speed railway track under passing axles as a function of speed and frequency is studied. The track deformation wave phenomenon of high speed railway is explained by the track deformation response calculated. In addition, the effects of track damping on the wave is discussed. It is shown that track damping is of fundamental importance in attenuating the wave and enlarging the critical speed.
