Nonlinear Dynamic Modeling of Constant Force Supported Thermal Power Pipeline

Abstract

In this paper, the Hamilton theory was applied to describe the dynamic model of Thermal Power Pipeline nonlinear fluid solid coupling vibration. The model includes the control equation of axial vibration and the transverse vibration of the pipeline, taking full account of the vibration characteristics of the fluid in the pipeline, effect of thermal deformation and constant support, as well as the friction coupling, Poisson coupling and junction coupling. The model is an attempt to the heating pipes and need to be further improved.
