Research on Equivalent Bending Stiffness of Conical Inflated Beam

Abstract:

The conical inflated beams have steady bending stiffness before wrinkles appear according to experimental load-deflection curve, then the deflection distribute function is derived based on the differential function of deflection with variable bending stiffness. The equivalent bending stiffness is presented while the conical inflated beam equates to cylindrical inflated beam, according to the deflection formula of beam, the model of equivalent bending stiffness of conical inflated beams is obtained. Comparing the equivalent bending stiffness of conical inflated beams between theoretical model and Experiment results, it is found that they agree with each other well.
