진동 보울피더에서 반복 충돌의 혼돈 동역학에 관한 실험적 연구 = Experimental Study of Chaotic Dynamics of Repeated Impacts in Vibratory Bowl Feeders

다국어 초록 (Multilingual Abstract)

The vibratory bowl feeder is the most versatile of all hopper feeding devices for small engineering parts and the typical nonlinear dynamic system experiencing repeated impacts with friction. We model and analyze the dynamic behavior of a single part on the vibration track of the bowl feeder. While the previous studies are restricted to the sliding regime we focus our analysis on the hopping regime where the high conveying rate is available. We present the numerical simulation and experimental results for dynamic behavior and conveying rate in the chaotic regime is more or less independent of variations of the external parameters. Simulation and experimental results agree well. This research presented the important features for the design of the vibratory bowl feeder and holds much potential for leverage over design problems of wide range of mechanisms and tools with repeated collisions.
