Active random vibration control for stochastic piezoelectric truss structures

This paper presents the optimization of the location and feedback gains of active bar in a closed loop control system for stochastic piezoelectric smart truss structures under stationary random excitation. The mathematical model with reliability constraints on the mean square value of the structural random dynamic displacement and stress response is developed based on maximization of dissipatio...

Suppression of Random Vibration in Flexible Structures using a Hybrid Vibration Absorber

Suppression of Random Vibration in Flexible Structures using a Hybrid Vibration Absorber M.H. Tso, J. Yuan, W.O. Wong Abstract A design method is proposed to suppress stationary random vibration in flexible structures using a hybrid vibration absorber (HVA). While the traditional vibration absorber can damp down the vibration mainly at the pre-tuned mode of the primary structure, active damping...

Free vibration analysis of steel framed structures

This study based on free vibration analysis and study the behavior of framed structure under different frequency of vibration using ANSYS software and shaking table. A small scale uni-axial shaking table was prepared in laboratory, which can produce lower to moderate vibration, regarding frequency and velocity. Moment resisting framed structures constructed with connecting beam and column eleme...
