摘要
本文对轴对称加肋旋转壳及其组合壳体(锥-锥,锥-柱,球-柱壳等)在轴对称静载荷作用下的线弹性强度和稳定性计算,采用性能良好的轴对称拟协调单元推导了有限元的计算列式,并将计算结果与静水压力下的锥-柱-锥结合壳,加肋锥-柱结合壳的其它计算结果和实验结果进行比较。
The finite element formulation for the linear elastic strength and instability analysis of ring-stiffened combined shell of revolution (cone-cone, cone-cylinder and sphere-cylinder etc) is proposed. The quasi-comforming element is adopted,which has the advantages of less nodal parameters, high computing accuracy and no sigularity at r = 0. The computing results are compared with other computing results as well as experimental results,
