What is a membrane air spring?
什么是膜式<a href='http://www.485353.cn/' target='_blank'><u>空氣彈簧</u></a>?
    膜式空氣彈簧的構(gòu)造是在金屬外筒與內(nèi)筒,或缸筒與活塞之間安放橡膠膜,通過膜的變型成功實(shí)現(xiàn)整體伸縮。在外筒的內(nèi)壁與內(nèi)筒的外壁上預(yù)先給出合適的傾斜或球面,據(jù)此橡膠膜伸縮時可沿該壁面發(fā)發(fā)生災(zāi)難形,受壓最簡單的面或物體表面的大小隨變型而變化。這就可以得到在定額高度下很軟,而在大位移時變硬的尤其的性質(zhì),即合適的非線性彈性尤其的性質(zhì)。膜式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.
