囊式空氣彈簧剛度簾線角度非線性性能介紹：
   Introduction to the angular nonlinearity of the air spring spring stiffness cord:

   1、當空氣彈簧垂直位移時，空氣彈簧的體積變化很大，產(chǎn)生明顯的垂直非線性特征;橫向位移時，空氣彈簧的體積變化很小，橫向特性是線性的。
  1. When the air spring is vertically displaced, the volume of the air spring changes greatly, resulting in obvious vertical nonlinear characteristics;Lateral displacement, the volume of the air spring  change very little, lateral characteristics are linear.
   2、空氣彈簧內(nèi)壓越大，垂直剛度越大，空氣彈簧內(nèi)壓對橫向剛度的影響越小。
   2, the greater the internal pressure of the air spring, the greater the vertical stiffness, and the smaller the impact of the internal pressure of the air spring on the lateral stiffness.
    3、簾線角度對垂直剛度和橫向剛度有很大影響，對膠囊的強度也有很大影響。工作過程的VS圖表明，繩索主要是由于繩索引起的。當角度不同時，當空氣彈簧變形時，體積和有效面積會發(fā)生變化，這會導致垂直和橫向特性發(fā)生變化，這不能通過經(jīng)驗公式反映出來。
   3. Cord Angle has a great influence on vertical stiffness and transverse stiffness, as well as on the strength of the capsule.The VS diagram of the working process shows that the rope is mainly caused by the rope.When the Angle is different, when the air spring is deformed, the volume and effective area will change, which will lead to a change in the vertical and horizontal characteristics, which cannot be reflected by the empirical formula.

   4、簾線密度和層間距離對膠囊的縱向剛度和橫向剛度影響不大，但對膠囊的強度影響較大。隨著臍帶密度的增加，各層間的距離逐漸增大。有效地降低了簾線層的最大應力。
   4. Curtain line density and the distance between layers have little influence on the longitudinal stiffness and transverse stiffness of the capsule, but have a great influence on the strength of the capsule.As umbilical cord density increased, the distance between layers gradually increased.The maximum stress of the cord layer is effectively reduced.
   5、簾線層數(shù)對垂向剛度影響不大，但對橫向剛度影響較大。增加簾線層數(shù)可以獲得較大的橫向剛度，并能有效降低簾線層數(shù)的最大應力。
