机车车辆减震器Absorber主要用来抑制弹簧吸震后反弹时的震荡及来自路面的冲击，将“大能量一次冲击”变为“小能量多次冲击”，车辆减震器由弹簧和减震器共同组成的。车辆减振弹簧有压缩弹簧、橡胶弹簧、复合弹簧和橡胶空气弹簧，有单筒气压减震器、双筒油压减震器、双筒油气减震器，车辆钢弹簧有螺旋形、碟形、环形和板形等。螺旋钢板减震弹簧和橡胶空气弹簧在高铁轨道车辆应用最为广泛。

钢丝减震压缩弹簧（压簧）是承受轴向压力的螺旋弹簧，减震压缩弹簧有圆柱形、圆锥形、中凸形和中凹形、非圆形等。橡胶空气弹簧俗称空气弹簧、橡胶气囊。橡胶减震弹簧是一种高分子弹性体,具有自生热小、回弹性好、机械性能稳定、使用寿命长。复合减震弹簧是由金属螺旋弹簧和橡胶复合为一体的弹性体,集金属弹簧和橡胶弹簧的优点于一体。复合减震弹簧能承受重载荷和大变形量,隔振降噪效果好、工作平稳、过共振区时间短等优点.常用于矿山冶金煤炭等行业的大型振动设备。
