空气弹簧刚度帘线角度非线性性能介绍

   囊式空气弹簧刚度帘线角度非线性性能介绍：
   Introduction to the angular nonlinearity of the air spring spring stiffness cord:

   1、当空气弹簧垂直位移时，空气弹簧的体积变化很大，产生明显的垂直非线性特征;横向位移时，空气弹簧的体积变化很小，横向特性是线性的。
  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、空气弹簧内压越大，垂直刚度越大，空气弹簧内压对横向刚度的影响越小。
   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、帘线角度对垂直刚度和横向刚度有很大影响，对胶囊的强度也有很大影响。工作过程的VS图表明，绳索主要是由于绳索引起的。当角度不同时，当空气弹簧变形时，体积和有效面积会发生变化，这会导致垂直和横向特性发生变化，这不能通过经验公式反映出来。
   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、帘线密度和层间距离对胶囊的纵向刚度和横向刚度影响不大，但对胶囊的强度影响较大。随着脐带密度的增加，各层间的距离逐渐增大。有效地降低了帘线层的最大应力。
   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、帘线层数对垂向刚度影响不大，但对横向刚度影响较大。增加帘线层数可以获得较大的横向刚度，并能有效降低帘线层数的最大应力。
