| 摘 要： | 采用有限元法研究了动力吸振器减小船体梁结构谐波振动响应的有效性。在本文研究中利用由文献[1]给出的最优调谐参数，采用直接法计算谐波激励下船体结构的频率响应特征。本文分析了动力吸振器三种不同配置的情况，用来研究它们对减小船体谐波响应的敏感性和适用性，为动力吸振器的实船应用提供了理论依据。

| Abstract: | The study of the effectiveness of the dynamic vibration absorber in reducing harmonic response of the ship hull girder using the finite element method is presented. The optimal tuning parameters suggested in reference [1] are adopted in this study. The direct method is used to calculate the frequency response characteristics of ship hull girder subjected to external harmonic force. Three different cases of dynamic absorber arrangements are analyzed to study their sensitivity and suitability in reducing the harmonic response of ship hull. |
