| 中文摘要: |
| 以柱状空气垫为研究对象，在几何压缩模型的基础上，基于准静态压缩中空气垫内气体变化为等温过程，建立了气垫静态刚度与气垫内初始相对内压、压缩变形量关系的理论模型；取规格不同、初始内压相近及规格相同、初始内压不同的空气垫，通过准静态压缩试验，得到了静态刚度并与理论值进行了比较。研究表明，当压缩量较小时，理论模型对空气垫静态刚度的预测较为准确。 |
| 英文摘要: |
| Column air cushion was taken as object of study. The theoretical model of the static stiffness, initial internal pressure and compression deformation were established in terms of the geometry model based on the isothermal process inside the air cushion. Static stiffness characteristics were obtained from quasi-static compression test, and comparison was made between the models and experimental values of the different specifications and initial internal pressures. The results showed that the static stiffness from theoretical model is more suitable for small compression deformation. |
