Abstract:The problem of impact rebound is of great significance for the motion and design of mechanical system which transmits energy by impact. Using wave theory, the rebound problem of impact mechanical system has been comprehensively analysed, and the rebound criterion of equal resistance impact system and the calculating formulae of rebound velocity have been established.
Key words: impact rebound wave mechanics
