摘　　要：以空气垫为研究对象,基于已有的压缩变形圆柱模型,提出新的空气垫几何压缩模型。采用准静态压缩试验,得到不同规格的空气垫压缩后的接触面积和压缩载荷特性,并与模型理论值比较。结果表明,圆柱模型适合表征尺寸规格较小的空气垫,而改进模型适合表征尺寸规格较大的空气垫。An existing geometry model, which treated the airbag as a horizontal cylinder, was used to explain the static loading property of the airbag. An improved model was proposed. The quasi-static compression was employed, through which the comparison was made between the models＇and experimental values of the contacting areas and static compressing curves. It was found that the horizontal cylinder model is more suitable for small size airbag; the improved model is more suitable for large size airbag.
