PARAMETRIC ANALYSIS AND RESPONSE SIMULATION OF SELF-EXCITED ICE-INDUCED VIBRATION OF OFFSHORE PLATFORM STRUCTURES

  • 摘要: 本文依据Maattanen的自激冰力模型,分析了冰和结构的各种参数对海冰作用下平台结构自激振动的影响;对不同动力特性的导管架平台结构简化模型,进行了海冰作用下结构自激振动响应的数值计算,发现了自激冰力和结构振动的一些特征,为进一步理解冰致平台结构自激振动现象,避免自激振动的产生及采取相应的控制措施提供了有益的结果。

     

    Abstract: 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 from the simulations some features of self-excited ice forces and structural vibrations were found. The results in this paper are useful for both promoting understanding of self-excited vibration and avoidance or control of this kind of vibration.
