INDEPENDENT MODAL CONTROL FOR VIBRATION SUPPRESSION

Abstract

Abstract: The problem on vibration suppression of the cantilever beam is Independent Modal Control Method (IMSC) .The structural dynamic mo- del has been formulated for the cantilever beam bonded piezocrystal sensors and actuators.The control testing for the first bending mode of a cantile- ver beam has been performed.The experimental results indicated that the damping ratio of first bending mode is increased,damping ratios for other modes are not changed,and the system is stabilized.

Key words: Structural vibration, Cantilever beam, Model control, Research
