本文提出了一种计算加筋圆柱圆柱壳固有频率的简明而全面的方法。该方法是基于一个能量泛函的公式，其中包括两个平面的弯曲能量和加强筋的旋转惯量。能量方程导致一个特征值问题，用计算机求解。对环加筋、弦加筋和正交加筋壳体进行了检验，并将预测结果与实测结果进行了比较。
This paper presents a concise yet comprehensive method for the determination of natural frequencies of stiffened circular cylindrical shells. The method is based on the formulation of an energy functional which includes energy of bending in two planes and rotary inertia of the stiffeners. The energy equations lead to an eigenvalue problem which is solved using a computer. Ring stiffened, stringer stiffened and orthogonally stiffened shells have been examined and predicted results have been compared with measured results.
