20kN雙筒減震器示功特性試驗機，測定減震器伸張行程及伸張阻力，壓縮行程及壓縮阻力，繪制力-位移變形示功曲線。廣泛應用于車輛懸架系統減振器和氣囊減振器測試研究。滿足GB/T13061-2017商用車空氣懸架用空氣彈簧技術規範；QC/T 62-2021摩托車和輕便摩托車減震器；
車輛在路面上行駛時，來自路面的沖擊經過輪胎首先傳導到懸架上，懸架的彈簧通過自身的形變吸收能量，但彈性原件耗散能量的過程比較緩慢，在能量釋放完之前，車身會反複回彈跳動。就是減震器主要是抑制彈簧的反複回彈並耗散掉彈簧形變的能量，將“大能量一次沖擊”變爲“小能量多次沖擊”，車輛減震器由彈簧和減震器共同組成的。車輛減振彈簧有壓縮彈簧、橡膠彈簧、複合彈簧和橡膠空氣彈簧，有單筒氣壓減震器、雙筒油壓減震器、雙筒油氣減震器，車輛鋼彈簧有螺旋形、碟形、環形和板形等。螺旋鋼板減震彈簧和橡膠空氣彈簧在高鐵軌道車輛應用最爲廣泛。橡膠空氣彈簧俗稱空氣彈簧、橡膠氣囊、氣囊等。
鋼絲減震壓縮彈簧是承受軸向壓力的螺旋彈簧，彈簧一般爲等節距的。減震壓縮彈簧有圓柱形、圓錐形、中凸形和中凹形、非圓形等。橡膠減震彈簧是一種高分子彈性體,具有自生熱小、回彈性好、機械性能穩定、使用壽命長。複合減震彈簧是由金屬螺旋彈簧和橡膠複合爲一體的彈性體,集金屬彈簧和橡膠彈簧的優點于一體。複合減震彈簧能承受重載荷和大變形量,隔振降噪效果好、工作平穩、過共振區時間短等優點。
