| Abstract: | nderwater suspended pipelines form a structure of one-span or multispan beam with reinforced pipelines. Vortex-excited vibration induced by fluid takes place on the underwater suspended pipelines. This paper presents the mechanical model of vortex-excited vibration for two kinds of structures and the analysis method of vortex driving vibration. It has been proved that the method is reliable through calculotions and experiments. |
