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.
