中文摘要：
采用加零变换法和变积方法，并考虑伴生力特性，建立了适用于非保守薄壁结构系统的广义拟余Hamilton原理。应用该原理解决非保守薄壁结构系统扭转动力学问题，给出同时求解薄壁结构的剪流和转角两类变量的计算方法，最后，讨论了相关的问题。
英文摘要：
Considering the characters of fellow forces, the generalized Hamilton-type quasi-complementary energy principle, that is applicable to thin-wall structure of non-conservative system, can be obtained adopting the zero-addition transformation method and the variational integral method. Appling this principle to the torsion dynamics problem of non-conservative thin-wall structural system, this paper develops the method that can calculate both the shear force and the rotation simultaneously. Finally some correlative problems are discussed.
