摘要
The paper addresses the dynamic interaction of an orthotropic cylindrical shell with the fluid flowing inside. Its velocity has a constant component and low-amplitude pulsations. A method to calculate the characteristics of the parametric vibrations of the shell when the velocity of the fluid is close to critical is proposed. The amplitude-frequency characteristics of the shell-fluid system at fundamental parametric resonance are determined. © 2009 Springer Science+Business Media, Inc.
