薄壁结构弯扭耦合振动分析

Analysis for Bending-Torsion-Coupled Vibration of a Thin-Walled Structure

本文考虑转动惯量、剪切变形和翘曲,讨论了用迁移矩阵法分析薄壁结构的弯扭耦合振动问题。文中讨论了断面突变处的协调条件及端部封板对振动特性的影响。算例表明,本文的理论和方法是可靠的。

This paper devotes to the analysis for coupled vibration of a thin-walled structure by using the trans-fer matrix method with considering shear deformation、warping and rotary inertia,the effect of the plate attwo ends and compatibility conditions between open channel segment and closed channel segment on thecoupled vibration is discussed.The results show that the theory and the method presented in this paper isreliable.
