摘要
应用文献［５］导出的锥壳屈曲分支方程，首次对铰支锥壳的扭转稳定性进行了研究根据分支点变形状态分析，设计了一组构形准确的屈曲模式通过３参量Ｇａｌｅｒｋｉｎ变分计算。
In application of buckling bifurcation equations of conical shells derived from the author the stability behaviors of hinged truncated conical shells subjected to the torsional couples are investigated for the first time.According to the analysis of bifurcation point deformations more accurate buckling mode is constructed.By the aid of three-parameters Galerkin variational method the ideal numerical solutions of torsional buckling are obtained.
