Research on vertical stiffness of belted air springs

A new vertical stiffness formula, including a term incorporating the rate of change of the effective area of a belted air spring, is established. Quasi-static vertical stiffness values are calculated using the formula. Four different experimental methods are used to study static and quasi-static vertical stiffness of a belted air spring. Results calculated using the formula are consistent with the experimental data. When the reservoir is small or the load is heavy, the static and quasi-static extents of vertical stiffness can be precisely predicted. Differences between theoretical and experimental results are also analysed. The authors study the influence of geometric parameters on vertical stiffness of a belted air spring. When a reservoir is added to decrease vertical stiffness, the authors show how to avoid negative stiffness.
