| 中文摘要: |
| 以柱状空气垫为研究对象，给出了空气垫动态刚度与气垫动态压缩变形量、初始相对内压关系的理论模型。取不同规格初始内压相近，以及相同规格初始内压不同的空气垫，通过动态压缩试验，得到了空气垫的动态刚度，并与理论模型进行了比较。试验结果表明，动态刚度的理论预测值较试验值大，相同规格的空气垫，随初始相对内压的增加，动态刚度增大，初始内压较小时理论值与实验结果吻合较好。 |
| 英文摘要: |
| Cylindrical airbag was studied and a theoretical model was proposed, which redefined the relationships among the dynamic stiffness, initial internal pressure and dynamic compression deformation. Dynamic compression test was carried out to get dynamic stiffness characteristics, through which comparison was made between the models and experimental values of different specifications and initial internal pressures. Experiment results showed that theoretical predicted value of dynamic stiffness is bigger than the tested data; dynamic stiffness increases along with the increase of initial internal pressure. Results from calculation and experiments are in good agreement when the initial internal pressure decreases. |
