摘要
本文在薄壁梁截面上采用线性插值函数来描述截面各点的纵向位移;基于哈密顿对偶体系,考虑薄壁梁的剪力滞后效应,导出薄壁梁自振特性的哈密顿方程;采用两端边值问题的精细积分法,确定方程的高精度数值解。
The linear interpolation was applied to describe the longitudinal displacement of the cross- section points in the cross- section. The Hamilton equation of the structure Natural vibration frequency of the thin- walled beam under considering the shear lag effect is derived based on the Hamilton dual system. The precise integration method is used to determine the high precise numerical solution of the equation.
