Vibration control of the finite L-shaped beam structures based on the active and reactive power flow
This paper analyzes the physical meaning of the active and reactive power flow in the finite L-shaped beams and studies the active vibration control of the structures based on the active and reactive power flow. The traveling wave approach is used to calculate the structural dynamic responses. Because the error of control force is inevitable in practical applications, the effects of the error of control force on the control results are studied. The study indicates that the error of control force has pronounced influence on the control results of the acceleration and reactive power flow. It is obvious that the reactive power flow can represent the vibration strength component of the complex intensity, and the active power flow strongly depends on the structural damping of the finite beams.
