Parametric analysis and response simulation of self-excited ice-induced vibration of offshore platform structures

In accordance with the self-excited ice force theory, which was proposed by Maattanen, the influences of various parameters of ice and structure on the self-excited structural vibration were investigated. For simplified structure models of different dynamic properties, response simulations of ice-induced vibration were performed, and form the simulations some features of self-excited ice forces and structural vibrations were found. The results are useful for both promoting understanding of self-excited vibration and avoidance or control of this kind of vibration.
