摘要

摘要: 借助参考直线坐标系，求解空间曲线结构在曲线坐标系中的几何方程．运用Hamilton原理推导空间螺旋曲线梁结构的运动方程．方程表明空间曲线结构4个自由度相互耦合，当结构退化为平面曲线结构时，两个相互垂直平面内的各自由度相互耦合．空间任意曲线梁结构的动力方程均可按照该文推导思路得出．对于水中悬浮隧道结构，可以忽略转动动能对振动的影响．

Abstract: In virtue of reference Cartesian coordinates,geometrical relations of spatial curved structure were presented in orthogonal curvilinear coordinates.Dynamic equations for helical girder were derived by Hamilton principle.These equations indicate that four generalized displacements are coupled with each other.When spatial structure degenerates into planar curvilinear structure,two generalized displacements in two perpendicular planes are coupled with each other.Dynamic equations for arbitrary curvilinear structure may be obtained by the method used.
