Abstract

Abstract: Based on piezoelectric sensor and high speed data acquisition card，a measuring system for the restitution coefficient of elastic collision is introduced，and it is verified by experiment. Based on USB-1616HS high-speed data acquisition card real-time capture collision signal between the ball and the plate，by processing the collected collision waveform sequence，the interval of collision time between two adjacent elastic collision is obtained，and then the coefficient of restitution can be calculated.The experimental results show that this measurement system has the characteristics of simple structure，clear principle and high precision.
