Simulation software for parts feeding in a vibratory bowl feeder

Abstract

This paper describes the development of three-dimensional (3D) computer simulation software to simulate parts feeding and orienting in a vibratory bowl feeder. A mathematical model of part motion and the interaction of the part with the orienting mechanism were developed. Based on the mathematical model, a 3D-simulation software has been developed using Java. The key technology involves 3D object modelling and collision detection, which were developed with Java 3D API. The simulation software can perform dynamic simulation of part motion and the interaction of simple parts with the designed orienting mechanism, therefore enabling the reliability and capability of the design to be assessed prior to fabrication. The computer simulation was verified by carrying out physical experiments in the laboratory. Good agreement between the results of the computer simulation and experiments was obtained.
