气体弹簧是在一个密封的容器中充入压缩气体，利用气体的可压缩性实现其弹簧作用的。这种弹簧的刚度是可变的，因为作用在弹簧上的载荷增加时，容器内的定量气体气压升高，弹簧的刚度增大。反之，当载荷减小时，弹簧内的气压下降，刚度减小，故它具有较理想的弹性特性。
研究设计气体弹簧，利用其低刚度获得较低的共振频率，从而获得舒适的运送效果。
The gas spring is researched and designed to acquired lower resonance frequency and best damping effect, which has low regimens.
计算了空气弹簧系统的垂向刚度，并分析了气体压力和帘线角对垂向刚度的影响。
The vertical stiffness of the air spring system was calculated, and the effects of air pressure and cord Angle on it were analyzed.
有限元计算结果表明，空气弹簧系统垂向刚度随气体压力的增加而增加，随帘线角的增大而略减小。
The results show that the vertical stiffness increases with an increase in air pressure, decreases a little with an increase in cord Angle.
