摘　　要：应用能量原理导出肋形板自振频率计算式,针对工程中肋形板不同的边界约束状况,给出振型试函数各种形式,指出该方法既适用于不同纵、横梁布置的板,也适用于板边各种支承情况,与有限单元法相比,无需计算机程序,计算过程简单易行。The paper induces the explicit formula of natural vibration frequency of rib plate by applying energy principle, shows various trial functions of vibration in light of various boundary constraints of rib plate in engineering, and points out that method is widely applicant, which is suitable not only in horizontal and vertical plate but also in various plates bearing. Comparing to finite element method, it has no calculation pro- gram with simple calculation process.
