In this paper, the different construction ,dimensions and stiffness characteristics of convoluted and rolling lobe air springs are studied. 為了深入研究汽車裝用空氣彈簧后對整車性能的影響，必須首先了解空氣彈簧本身具有的特性，其中剛度特性尤為重要。
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. 根據展開和收攏幾何特性關係，對其剛度特性進行了分析，並依據彈性穩定理論，對該展開機構進行了局部和整體穩定性分析。
