After the introduction of the innovations and the improvements of foreign hydraulic shock absorbers, the profound cushion mechanics study is done aiming to the shock absorbers chosen for the thesis ; the cushion process of hydraulic shock absorbers can be divided into several stages, which include local pressure loss caused by across sectional area shrinking, sharp edge throttling and aperture throttling
在對國外新型液壓緩沖器的研究基礎上，針對本課題所選液壓緩沖器的結構特點，提出了分階段建立機理數學模型方法。將液壓緩沖器緩沖過程分為：由於流道斷面突然收縮引起的局部壓力損失階段，緩沖柱塞的邊緣和緩沖孔的邊緣形成銳緣節流階段，當緩沖柱塞進入緩沖孔中形成的縫隙節流階段等三過程。
