前言在近年来新制的高速电动车辆的转向架上,一般都采用空气弹簧装置,这对改善车辆在高速运行时的稳定性及舒适性,有着显著的作用。而在过去制造的旧型转向架中,叠板弹簧还是占绝对多数,这种转向架占现有车辆的半数以上,由于叠板弹簧转向架在高速运行时,其稳定性及平稳性方面存在着 Preface In recent years, newly-built high-speed electric vehicles bogies, air springs are generally used, which has a significant role in improving the stability and comfort of vehicles in high-speed operation. In the old bogies made in the past, laminated springs still accounted for an absolute majority of such bogies accounted for more than half of the existing vehicles, as the stacked spring bogie at high speeds, its stability and stability there
