20kN双筒减震器示功特性试验机，测定减震器伸张行程及伸张阻力，压缩行程及压缩阻力，绘制力-位移变形示功曲线。广泛应用于车辆悬架系统减振器和气囊减振器测试研究。满足GB/T13061-2017商用车空气悬架用空气弹簧技术规范；QC/T 62-2021摩托车和轻便摩托车减震器；
车辆在路面上行驶时，来自路面的冲击经过轮胎首先传导到悬架上，悬架的弹簧通过自身的形变吸收能量，但弹性原件耗散能量的过程比较缓慢，在能量释放完之前，车身会反复回弹跳动。就是减震器主要是抑制弹簧的反复回弹并耗散掉弹簧形变的能量，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。橡胶空气弹簧俗称空气弹簧、橡胶气囊、气囊等。
钢丝减震压缩弹簧是承受轴向压力的螺旋弹簧，弹簧一般为等节距的。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。
