摘　　要：船舶推进系统-船体的动力学耦合理论是适应船舶大型化发展趋势和提高大型船舶航行性能的理论基础,需要解决大型船舶的大尺度效应、多参数耦合作用以及不确定航行环境与状态对船舶推进系统影响的理论问题,并探索通过改善推进系统的自适应性和工作可靠性来提升船舶航行性能的方法。文章侧重从大型船舶推进系统的状态不确定性分析与评估、水环境—船体—推进系统动力学耦合作用、以及船舶的实验室试验性能与实海环境的航行性能不一致性等三个方面,综合分析了国内外在该领域研究进展,指出尚待解决的问题和今后的研究方向。This paper reviews theory and methodology that were developed to cope with the matching opti- mization of the ship propulsion system and hull. The recent advancement on the strip theory for the forecasting of hull deflection under various wave loads, and the impact of the hull deformation on the propulsion shaft line are discussed. The advantages and shortcomings of traditional shafting alignment techniques are reviewed and illustrated through examples. Applications and the state of-the-art in advanced shafting dynamic alignment are also reviewed. Finally, several main areas for future development in this field are discussed. These include development of the precise modeling theory of the large ship propulsion system under uncertainty, the coupled dynamic modeling method for the large ship propulsion system and hull deflection, and the optimization database for the coupling design of the propulsion system and ship tvoe.
