This paper constructed a bulk carrier's ID beam model and mixed finite element model. Basing on the global vibration analysis, we compared and researched three different methods of adding propeller exciting force, calculated the forced vibration response of the aft structures and the superstructure , and then evaluated the vibration level. The results indicate the vibration characteristic of the bulk carrier is satisfying. This paper is valuable for the evaluation on vibration and response analysis of bulk carriers.%针对某散货船建立一维梁模型和混合有限元模型.在总振动计算的基础上,对3种不同的螺旋桨激振力的施加方式进行比较研究,计算其尾部及上层建筑的强迫振动响应,最后根据船舶振动基准进行振动评价.计算结果表明,该散货船的振动特性良好,对该类型船舶的振动和响应预报具有一定的参考价值.
