Ice-induced vibrations and scalingScienceDirect

 · 1.. IntroductionIce-induced structural vibrations have been observed by many people starting with the classical work of Blenkarn (1970) in the Cook Inlet. A limited number of full-scale observations have been made though regrettably it has not always been possible to measure and record critical parameters such as the ice thickness and the ice velocity.

In such a limit state of vibrations the net energy inflow during each vibration cycle is zero while all the energy input from ice pushing is dissipated into ice crushing and structural damping. The origin of ice induced structural vibrations has been under dispute for over 40 years.

On a simple oscillator problem describing ice-induced

 · In this paper a new simple oscillator model is considered describing ice-induced vibrations of upstanding water-surrounded and bottom-founded offshore structures. Existing models are extended by taking into account deformations of an ice floe and a moving contact interaction between an ice rod which is cut out from the floe and the oscillator which represents the offshore structure.
