1、自動(dong)變(bian)速箱(xiang)油(automatic?transmission?fluid,atf)是自動(dong)變(bian)速汽車(che)中的(de)關鍵潤滑(hua)劑(ji),它不僅承擔著潤滑(hua)、冷卻和清潔(jie)的(de)作用,還直接影(ying)響到汽車(che)的(de)駕駛舒(shu)適(shi)性(xing)。在自動(dong)變(bian)速箱(xiang)油的(de)性(xing)能評價(jia)中,抗顫性(xing)是一個重要的(de)指標(biao),它關系到駕駛過程中的(de)平(ping)穩性(xing)。

2、現有(you)的摩擦試驗(yan)機主要用于測(ce)(ce)試材料的摩擦系(xi)數,但并沒有(you)專門針(zhen)對atf抗(kang)顫性能(neng)測(ce)(ce)試的設備,無法(fa)模擬atf在實際變(bian)速箱(xiang)中的工作(zuo)狀態。
