摘　　要：对具有变厚度的夹层环形板大挠度问题进行了研究.采用打靶法和解析延拓法求得了具有双曲型变厚度夹层环形板在外边缘为可移夹紧固定、内边缘与一刚性中心固结情况下非线性弯曲问题的数值解,并讨论了几何参数和物理参数对夹层环形板弯曲问题的影响,给出了特征关系曲线,结果可供工程设计参考.The problem of large deflection of the annular sandwich plate of variable thickness was studied.By using the shooting method and the analytical continuation method,the numerical solution of the nonlinear bending was found.In addition,we discussed the bending problem influenced by geometric and physical parameters.Finally,the characteristic curve was given as a reference for engineering designs.
