The approximate formula^ guarantees very good accuracy for low modes. (4)Considering the interaction between fluid and structure ,it is more reasonable to apply the intercross method to calculate the mode and frequencies of the stiffened rectangular plates contacting with water.
综合全文，结论如下：(1)程序计算结果表明，用板梁组合结构模拟加筋板结构是正确合理的；加筋板结构单面或双面与水接触时的计算方法是有效的；(2)程序实现了从加筋板结构中识别板的模态，这对预防和控制加筋板结构的振动有着重要的实际意义；(3)运用近似计算公式求解流体附连水质量，在低阶模态下可以保证有足够的精度；(4)考虑流场与结构振动的交互作用，应用交叉迭代技术求解耦合振动频率和振型，分析结果理论上更符合实际情况。
