Introduction to the angular nonlinearity of the air spring spring stiffness cord:
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, 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. 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. 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. The number of cord layers has little influence on vertical stiffness, but great influence on transverse stiffness.Increasing the number of cord layers can obtain greater lateral stiffness and effectively reduce the maximum stress of cord layers.
