摘要
在阐述了用于高速车辆动态仿真的轨道谱特征基础上,着重分析了美国轨道谱与高速轨道谱之间的关系,论证了后者是在前者的基础上发展起来的,提出了实物振动试验台可用美国6级轨道谱缩减系数方法实现高速轨道谱对机车车辆的激振,这一方法已在实物试验中应用。
The characteristics of track PSDs for dynamic simulations of highspeed vehicles are described. The PSDs relations between the U.S. railways and the highspeed railways are emphasised. A minification coefficient method using the U.S. track PSDs is proposed to realize the stimulation of highspeed vehicles on a test rig, and this method has been applied in practice.
