Analysis of natural vibration frequencies of thin multilayer pipes of the reinforced plastics

,

Abstract:

The results of numerical studies of natural frequencies and mode shapes of multi-layer straight tubes, depending on the parameters of the reinforcement, the length and boundary conditions, reflecting the consolidation conditions. Based polubezmomentnoy theory of thin shells and Lagrange equations of the second kind, a formula for natural frequencies of oscillation of the pipe under pressure. The results of calculations performed on the basis of a structured approach and the finite element method are compared with those of a number of known solutions and experiments.
