摘要
提出一种基于有限元结构动力分析的船体板架固有频率实用修改方法，并进行了软件设计。该法适用于船体板架尺寸、激励频率不易改变的调频情况。
Authors suggest a practical method based on dynamic analysis of finite element for modifying natural frequencies of hull grillage beam, and its software is completed. The method can be applied when the size of hull grillage beam and exciting frequencies cannot be easily changed.
