THE SEMI-ACTIVE CONTROL OF SHAPE MEMORY ALLOY COMPOSITE BEAM

  • The dynamic model of a hybrid composite beam vibrationcontrol using shape memory alloy(SMA) is analyzed. This model isdeveloped based on the one-dimensional SMA constitutive equation and multicellmodel, and considers the influence of transverse shear deformation of thehybrid composite beam. Semi-active control can reduce the response of theconstruction by changing its parameter. According tothe switch control theory, the control law can be determined and then thesemi-active control simulation is carried out. The numerical results show that thesemi-active control is an effective way for SMA fiber composites.
