    膜(mó)式(shì)空(kōng)氣彈簧的(de)構造是在金屬外(wài)筒與內筒,或缸筒與活塞之間安(ān)放橡膠膜,通過膜的變型成(chéng)功實(shí)現整體伸縮。在外筒的內壁與(yǔ)內筒的外壁上預先給出(chū)合適的(de)傾斜或球麵,據此橡膠膜伸縮(suō)時可沿該壁麵發發生災難形,受壓最簡單的麵(miàn)或物體表麵的大小(xiǎo)隨變型而(ér)變化(huà)。這就可以得到在定額高度下很軟,而在大(dà)位移時變硬的尤其的性(xìng)質,即合適的非線性彈性尤其(qí)的性質。膜式(shì)空氣彈簧又分為約束膜式和自由膜式。
   
The construction of membrane air spring is to put rubber film between the metal outer cylinder and inner cylinder, or between cylinder and piston, and achieve overall expansion and contraction through the variation of the film.The inner wall of the outer cylinder and the outer wall of the inner cylinder are pre-provided with an appropriate inclination or sphere, according to which when the rubber film expands and contracts, the disaster shape can occur along the wall surface.This leads to the special property that is soft at a fixed height and hard at a large displacement, that is, the special property of suitable nonlinear elasticity.Film type air spring is divided into constrained film type and free film type.
