Abstract

The governing equation of pipe conveying fluid was deduced based on Timoshenko beam model. Wave method was applied to solve the governing equation. In the process, wave reflection matrices were obtained for three typical boundary conditions and the wave scattering model was established for the intermediate elastic support. Based on the above model, the wave characteristic equation for pipe conveying fluid with intermediate elastic support was obtained through wave train closure principle. In the example, the natural frequencies and critical fluid velocities were calculated for pipe conveying fluid with the intermediate elastic support at different locations.
