摘　　要：联合采用可压缩流体的边界元法与轴对称弹性薄壳的改进多节传递矩阵法,求解内部充液的椭球壳的耦合振动。数值计算结果表明,内部充液对壳体振动的耦合作用较强;壳体厚度与扁平度不同的椭球薄壳,耦合作用强度有较大差别。The boundary element method(BEM) fot compressible fluid and the improved multi-segmental transfer matrix method of thin, elastic axisymmetric shells is employed to solve the coupled vibration of shell filled with fluid. Nume-rical results show that the coupling effects on shell vibration are rather strong,and differ significantly for different geometry or structure.
