Rebound resilience test stand / for rubber

The resilience of rubber is calculated as the ratio of rebound height of a mass to drop height. Numerous designs of apparatus have been produced including the Lüpke Pendulum and the Dunlop Tripsometer.

All are subject to errors due to air resistance, friction in moving parts, vibration in the apparatus and whip due to elasticity in solid pendula. All require a considerable degree of operator skill if acceptable results are to be obtained and all are tedious to operate.
The ratio of rebound height to initial drop height is equal to the ratio of the kinetic energies after and before impact. This in turn is equal to the square of the ratio of velocity after and before impact. Thus by measuring the velocity immediately before and after impact the resilience can be readily computed.
