The process of converting a randomly oriented set of parts (as obtained from a vendor) into an ordered array is called parts feeding. There are many different types of feeders and feeding techniques used in the industry. This paper deals with a particular feeding process referred to here as vibratory entrapment. It describes a particular cause of failure of vibratory entrapment, namely, resonance. Failure due to resonance was first observed in high-speed video images of the entrapment phenomenon. This paper provides a description of the mechanics of failure of entrapment due to resonance. The mechanics is introduced with the simple example of a ping-pong ball in a cup and extended to real parts in a parts feeder. Conditions for resonance are derived and experimentally verified for a simple part shape and vibration pattern.<\/jats:p>","DOI":"10.1177\/02783640022066969","type":"journal-article","created":{"date-parts":[[2004,12,17]],"date-time":"2004-12-17T20:23:10Z","timestamp":1103314990000},"page":"448-466","source":"Crossref","is-referenced-by-count":0,"title":["Resonance-Induced Failure of Entrapment: Application to Industrial Parts Feeding"],"prefix":"10.1177","volume":"19","author":[{"given":"Jayaraman","family":"Krishnasamy","sequence":"first","affiliation":[{"name":"Brooks Automation Inc., Chelmsford, Massachusetts, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark J.","family":"Jakiela","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Washington University St. Louis,                         Missouri, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2000,5,1]]},"reference":[{"key":"atypb1","unstructured":"Brost, R. 1992.
