摘要 针对冰与结构的相互作用问题进行了分析研究。在 Sodhi模型的基础上提出一种新的冰与结构的耦合振动模型。通过引入冰板破坏长度的特征参数 ,将冰与结构的耦合作用分为加载、穿透和分离三种典型状态 ,给出了各种状态下的运动方程和求解方法及不同状态间的转化关系 ,从而获得结构冰致振动的稳态周期响应 ,并运用这一模型对结构与冰的各种参数的影响作了系统研究。结果表明 ,本模型适用于相当宽的冰和结构的参数范围及冰板弯曲和屈曲的不同破坏方式 ,模型易于向多自由度系统推广。 WT5”BZ]A new ice structure interaction model is developed on the basis of Sodhi′s model. By introducing the broken length of ice sheets, the ice structure interaction is divided into three phases: loading, extrusion and separation. The equation of motion and the solution for each phase are given in detail and the various demensionless parameters related to this model are studied systematically. The model is deduced for the single degree of freedom system and can be applied in the multi degree of freedom system accordingly. [WT5”HZ]
