铁路机车、车辆沿轨道高速运行时,由于机车、车辆和轨道的相互作用,二者作复杂的振动。多年来,人们对铁路轨道的振动,进行过不少的研究工作,其中轨道振动阻尼是人们关心的重要问题之一。以往,对轨道的振动阻尼往 When locomotives and vehicles run at high speed along the track, they are subjected to complex vibrations due to the interaction of locomotives, vehicles and rails. Over the years, people have done a lot of research work on the vibration of railway tracks, among which the orbital vibration damping is one of the important issues of concern. In the past, the orbital vibration damping to
