A simple yet efficient impact damper consists of a bed of granular materials moving in a container mounted on a primary vibrating system. This report deals with the damping performance of plural dampers applied to a multi-degree-of-freedom system. The impact vibration model including motion forms of riding or separation of the damper masses is developed, and the resulting formulation is analyzed by means of the modal synthesis method. The motion forms and their transitions are identified through digital simulation. Results of numerical studies, applied to a three-degree-of-freedom system, agreed well with those of experiments. It is found that plural impact dampers with properly selected mass ratios effectively suppress the resonance peaks over a wide frequency band.
