有间隙拱型结构的扭弯耦合振动非线性分析

ANALYSIS OF THE NONLINEAR OF THE TORSION FLEXURE COUPLING VIBRATION OF THE ARCH STRUCTURES WITH GAP

利用有限元数值计算与解析分析相结合的方法，通过对带间隙的拱型构件的振动分析，研究了拱型结构件在两端约束存在间隙时的扭弯耦合非线性振动特性，提出了数值解析法，并得到满意的结果。

In this paper,by means of the method of combined FEM numerical with analytical,when there are gaps at two restraint end of the arch structures,study special characteristic of the nonlinear of torsion flexure coupling vibration of which.A method of the numerical and analytical was put forward,The results of which are satisfactory,and it provides a new way to deal with the dynamics of such system.
