Motion System Design

Get a grip on gear noise

Two new courses in March 2010 aim to teach gear designers, noise specialists, and others interested in gear issues the fundamentals of working with gear noise. Both courses will be held at The Ohio State University in Columbus. The Basic Gear Noise Short Course, to be held March 17 to 19, 2010, has been offered for more than 30 years and is considered extremely valuable for those who encounter gear noise and transmission design problems. Attendees will learn how to design gears to minimize the major excitations of gear noise, including transmission error, dynamic friction forces, and shuttling forces. Fundamentals of gear noise generation and measurement will be covered along with topics on gear rattle, transmission dynamics, and housing acoustics. This course includes extensive demonstrations of specialized gear analysis software in addition to the demonstrations of many Ohio State gear test rigs. Also included is an interactive workshop session that invites attendees to discuss specific gear and transmission noise concerns.

Taking place March 22 to 23 is the Advanced Gear Noise Short Course, an extension of the basic course. This will be taught through lectures on selected topics and a series of hands-on workshops. Based on their interests, attendees may select from the following topics: Analytical and computer modeling, including whine prediction, general system dynamics, bearing/casing dynamics, gear rattle models; or experimental and computational approaches, which includes modal analysis of casings, acoustic radiation, advanced signal processing, sound quality analysis, and transmission error measurement.
