摘　　要：针对首艘内河电力推进豪华游轮中、艉部区域出现的有害振动问题,采用MSC-PATRAN软件等对游轮整体及局部结构进行仿真计算;对结构总体及局部的激励源、振动形式及固有频率进行了研究,并与实船试验数据对比分析,验证了理论分析及数值仿真计算的可靠性;进一步总结探讨引起该船在振动方面出现问题的原因,并提出了相应船舶减振的建议措施。For the stern area harmful vibration problems of the first river electric propulsion luxury cruise ship,the simulation calculation for ship whole and local structure was carried out by MSC PATRAN software; the overall structure and local excitation source,vibration mode and natural frequency were studied. Comparative analysis was carried out between the experimental data and the measured data,which verified the reliability of the theoretical analysis and numerical simulation.Furthermore,the causes in terms of vibration problems were summarized,and the corresponding ship vibration optimization measures were put forward.
