摘要
单跨和多跨水下悬空管线在水流作用下发生涡激振动．本文提出涡激振动的力学模型及涡激强度分析方法．最后通过实例计算和实验，验证了该算法的可靠性．
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.
