Mechanical Property and Ultimate Bearing Capacity of Ship Airbags

Abstract

Abstract:

The general geometry deformation and principle of thin shell pressure container etc were studied. A mathematical model of deformation, bearing force and inner air pressure of a loaded airbag was built. The membrane material property was determined by the uniaxial tensile test. The unified model could predict mechanical property and ultimate bearing capacity of the loaded airbag. Some cases were calculated and compared with the experimental data. The model was validated as a guidance for safety launching application.

Key words: ship airbags, mechanical property, ultimate bearing force, uniaxial tension test
