Natural frequencies of thin-walled composite cantilever box beams with SMA fibers

REN Yong-sheng,WANG Xiao-hui(College of Mechanical and Electronic Engineering,Shandong University of Science & Technology,Qindao 266510,China)  
The natural vibration behavior of thin-walled composite cantilever beams with SMA fiber actuation was studied.The coupled equations of free vibration of active anisotropic thin-walled box-beams incorporating SMA fibers were derived using the active two-dimensional analysis model developed based on Hamilton's variational principle.The general form of coupled equations of motion was applied to the cases of circumferentially uniform(CUS) and circumferentially antisymmetric(CAS) fiber installation.Closed form expressions for natural frequencies,corresponding respectively to the extension-twist coupling vibration and bending-twist coupling vibration were provided.Numerical studies were presented to compare the proposed model with the previously established passive model.The effects of SMA actuation and elastic coupling on frequencies were evaluated.
