摘要
采用Ｆｌｕｇｇｅ’ｓ壳体理论，对两端简支环加筋壳体在静水压力作用下的振动特性进行了研究，分析了静水压力及其变化对加筋壳体振动特性的影响，探讨了内压、外压及轴向压力对环加筋壳体固有频率的影响．
On the basis of Flugge's shell theory, a study was made on analysing vibration characteristics of ring-stiffened shell in simple support condition. The effects of hydrostatic pressure and its changes on vibration characteristics of ring-stiffened shell were analysed, the effects of inner pressure, outer pressure and axial pressure on inherent frequency of ring-stiffened shell were discussed.
