A new type impact damper consists of a bed of granular materials moving in a container fixed to the primary vibrating system. The problem is to determine the characteristics of the impact damper for reducing the vibration of the system to a prescribed value. This report deals with the indicial response of the damper, i.e., the damping characteristics of free oscillations from an initial displacement of the vertical and horizontal vibrating system. Experimental models were tested and numerical analyses were made to find the damping characteristics for several values of mass ratio and clearance. The results of numerical analyses agreed well with those of experimental tests.
