| Abstract: |
| The nonlinearity of the material，geometry and contact condition of air-bag used for ship launching was analyzed.Numerical simulation was carried out to analyze the relationship between inner and outer stress of the air-bag and compressive displacement by using the commercial nonlinear finite element analysis software MSC.Marc.The comparison between simulation and experiment results indicated that the method had high precision.The stress distribution of cord and rubber was also analyzed，which provided the basis for air-bag design. |
