摘要
在预测船体冰阻力数值方法中,有许多不同的公式可以用来估算不同冰况下工作的船体冰阻力。其中模型试验仍将是最准确的预测,但其他的一些方法也可以给冰阻力的估算提供依据。对破冰船的破冰方式在破冰过程中所受的阻力进行分析,探讨其在不同冰况下的冰阻力成分,分析各种冰阻力计算公式,然后对1艘破冰船进行实际计算,最后分析各公式计算结果以及各种方法的优缺点及适用范围。
The thesis is mainly about the ice-breaking ways and the ice-resistance of the icebreaker. Today one can predict the ice-resistance in different ice condition. Research on ship operating in ice the last decades has resulted in many different methods for predicting ice resistance on a ship hull. Analytical and numerical methods are developed to estimate the resistance. Although model test will still be the most accurate prediction, the other methods may also give you some guidelines. Different analytical ice resistance calculation methods are described and compared with each other in this thesis.
