船舶波激振动研究进展

摘要

随着船舶大型化的发展，高强度钢的大量使用，对于船舶长度超过300 m以上的大型船舶来说，波激振动现象逐渐突出。波激振动是一种高频谐振，它对船体结构的疲劳寿命产生重大影响。文章从理论预报、模型试验和实船测试三个方面对船舶的波激振动现象进行综合性的阐述，并提出当今船舶波激振动领域的研究展望。%With the development of ship turning into large scale and widely using of high strength steel, springing behavior appears more and more frequently in large ships which are traveling at sea, especially those of ship length more than 300 meters. The springing is a resonance with high frequency, which will take important influence on fatigue life of ship structure. In this paper, theoretical predictions, model tests and full scale measurements of springing behaviors on ships are reviewed systemically. Furthermore, prospect of the study of springing on ships is advanced.
