| 中文摘要: |
| 根据薄膜理论和网格理论，考虑帘线的强度、密度、缠绕角度及其几何结构的影响，得到帘线缠绕橡胶气囊在内压作用下的纵向应力和周向应力，进而推导出其爆破压强的计算公式。通过爆破压强理论值与模型试验值的对比，验证了计算公式的精确性。 |
| 英文摘要: |
| Based on membrane theory and netting theory， and considering the strength， winding density，winding angle and geometric structure of the cord，the formula to calculate the longitudinal stress，circumferential stress and burst pressure of cord wound rubber air-bag under internal pressure were obtained. The accuracy of the formula was good confirmed by comparing test value with theoretical value of burst pressure. |
