Abstract

The bending vibrations of a pipeline under the influence of the variable pressure of the transported fluid and the vertical vibrational movement of the supports are studied. The first vibration mode is considered. Nonlinear forced parametric vibrations and their interaction are studied. The results of approximate analytical and numerical solutions are compared.
