| 摘 要： | 采用有限元法对209000 DWT Newcastle-Max型散货船的船体梁振动特性和上层建筑在主机激励下的强迫振动响应进行数值分析。重点研究船体梁振动力学模型建模、主机机架振动计算和不平衡力矩加载等关键技术，对典型减振装置--平衡补偿器和顶部支撑的减振效果进行评估。计算表明，该船采取的减振措施效果显著，振动性能满足ISO 6954的振动评价标准。

| Abstract: | The finite element method is used for numerical analysis of overall vibration characteristic of the girder and forced vibration response the superstructure of a 209000 DWT Newcastle-Max type bulk carrier induced by main engine exciting force. Some key techniques, such as the mechanical modeling for vibration analysis, calculation of main engine frame vibration and the exciting force application method, are discussed. The vibration reduction effects of the balance compensator and the top bracing are evaluated. The results indicate that the vibration characteristic of this bulk carrier can meet the requirement of ISO 6954 standard by using the vibration reduction method. |
