Conveying can be achieved through the motion of objects on vibrating structural surfaces. With the rapid development of mechanical automation and intelligence,this technology is facing more requirements and challenges. This type of conveying equipment can generally be simplified as a motion model of bouncing balls on a vibrating thin plate surface. This article designs and builds an experimental platform for the dynamic behavior of a bouncing ball-thin plate system at a micro/macro-scale using an ideal ball-thin plate collision theoretical model. By using sound pressure sensors and data acquisition instruments to extract and process the sound signal of the ball hitting the thin plate,the effects of excitation frequency,amplitude,and ball mass on collision interval and strength are analyzed. The results show that the collision interval and collision strength between balls and thin plates are not fixed values,but exhibit a state with a single peak value. As the frequency and amplitude increase,the collision interval and collision intensity between balls and thin plates increase. Increasing the mass of the ball results in a decrease in both the collision interval and collision intensity,and such a change is a relative trend reflected by the mean,rather than a strictly absolute change. Specifically,it is found in the experiment that the waveform of the collision time between the ball and the thin plate is not instantaneous,but has a period of time effect,which is related to not only the coupling effect of the collision between the ball and the thin plate,but also the attenuation of the forced vibration of the thin plate under the impact of the ball.
