本文基于极地船舶挤压破冰的物理场景，开展冰体准静态压溃破坏模式下的载荷特性研究。完成冰试件的单轴压缩试验和弯曲试验，获取试验室制冰工艺所得冰体的压缩强度和弯曲强度；分析冰体模型准静态压溃失效过程中的载荷-位移曲线、冰体模型和加筋板接触面的压力分布及冰体模型的失效模式。本研究可为极地船舶在冰区航行时挤压破冰场景下冰荷载预报提供参考。
Based on the physical scenario of ice breaking by polar ships, the load characteristics of ice body under quasi-static crushing failure mode are studied in this paper. The uniaxial compression test and bending test of ice samples are completed. The load-displacement curve of the ice model, the pressure distribution of the contact surface between the ice model and the stiffened plate and the failure mode of the ice model are analyzed. This paper provides a reference for ice load prediction under the ice breaking scenario of polar ships sailing in the ice region.
