| 目的 研究柱形空气垫静态压缩缓冲性能，将理论几何压缩模型进行试验验证，证明可行性。 方法 根据柱形空气垫受压变形特征，推导出几何压缩模型理论公式，对不同宽度、不同充气压强的柱形空气垫进行静态压缩试验，用拓色法计算理论面积，将试验曲线与理论曲线进行对比。结果 随着压缩位移的增加，接触面积曲线的理论值与试验值呈线性关系，在宽度相同的情况下，充气压强的增大导致接触面积曲线的理论值与试验值吻合程度下降；相同宽度、不同压强的柱形空气垫载荷位移曲线很接近，显示出规格才是影响柱形空气垫缓冲性能的主要因素。结论 所提出的柱形空气垫静态压缩几何模型可行。 |

| The work aims to study the static compression cushioning performance of cylindrical air cushion, and ex-perimentally verify the theoretical geometric compression model to prove the feasibility. Based on the compressive de-formation characteristics of cylindrical air cushion, the geometric compression theoretical formulas werederived. Static compression tests were performed on cylindricalair cushions of different width and different inflation pressures. The the-oretical area was calculated by the color extension method, and the experimental curve and the theoretical curve were compared. As the compression displacement increased, the theoretical and experimental values of contact area had linear relationship. The increase of inflation pressure led to decline of the fit degree under the same width. The load and dis-placement curves of cylindrical air cushions with the same specifications and different pressures were very close, indi-cating that the specifications were the main factors affecting the cushioning performance. The static compression geometric model of cylindrical air cushion proposed in this work is feasible. |
