In this paper, the different construction ,dimensions and stiffness characteristics of convoluted and rolling lobe air springs are studied. 为了深入研究汽车装用空气弹簧后对整车性能的影响，必须首先了解空气弹簧本身具有的特性，其中刚度特性尤为重要。
The stiffness analysis was investigated with the geometric relations of deployment and stowage.And the local and whole stability analyses were also studied with stability theory. 根据展开和收拢几何特性关系，对其刚度特性进行了分析，并依据弹性稳定理论，对该展开机构进行了局部和整体稳定性分析。
