The new type of 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 prescrived value. This report treats with the indicial response of the damper i.e. the damping characteristics of free oscillations from initial displacement of the vertical and the horizontal vibrating system. Experimental models were tested and numerical analyses were developed to find the damping characteristics for several values of mass ratio and clearance. Results from numerical analyses agreed favorably with experimental tests.
