 equivalent damping
 The effects of a small "artificial" damping on the response, and the possibilities of an "equivalent" damping for the friction-affected constraints are also examined. An increase in the kinematic viscosity of the filling liquid, or a decrease in the size of the particles of the filling solid, will result in a corresponding increase in the equivalent damping factor of the system. This was evidenced by the measurements of the energy absorbed in the hysteresis loops, equivalent damping, and the stiffness and damping obtained from the free-vibration test. It is shown that the equivalent damping ratio increases inproportion to the square of frequency. The concept of an equivalent damping related to the delay feedback is proposed and the appropriate choice of the feedback gains and the time delay is discussed from the viewpoint of vibration control. 更多
