摘要
为评估极地破冰船在敞水中的动稳性的安全水平,并为未来新船型的开发积累经验,采用国际海事组织(IMO)第二代完整稳性衡准中的薄弱性衡准方法对2种不同尺度的设计方案开展动稳性敏感性评估。研究结果表明,现有设计方案对参数横摇和过度加速度失效模式表现出了一定的敏感性。通过分析诱发敏感性的船型设计参数,指出了未来优化研究的方向。
The dynamic stability performance of ship is of great significance to ensure the safety of ship sailing in harsh sea conditions.In order to assess the safety level of polar icebreaker and collect experience for further development of new ship design,the second generation stability criteria developed by International Maritime Organization(IMO)is adopted to assess the dynamic stability vulnerability of two different scale conceptual design plans.The results show that the current conceptual designs are vulnerable to the failure models of parametric roll and excessive acceleration.By analyzing the design parameters that induced the vulnerability,the direction of optimization research for future work is pointed out.
