Abstract

The importance of studying dynamic aspects of gear transmissions has been well established since many years; however, recently a new interest on this topics grew up because of significant improvement in gear design technology. The literature can supply different approaches to evaluate the vibrations response of simple and complex gears system. Numerical and analytical methods can provide important information on resonances, non linear behaviours and combined dynamic interactions in existing systems. In particular the reduction of vibrations is strictly related to minimize the value of the peak to peak of the static transmission error in a mesh cycle, through modifications of the tooth profile. The present paper combines a numerical model to study spur gear pair dynamics, with a genetic optimization technique to define the best profile modification capable to reduce the vibration. The numerical model is able to take into account gear geometry, profile modifications and profile manufacturing errors. The genetic optimization routine can provide the best set of profile modification considering the peak to peak value of the static transmission error or a generic number of its harmonic components. In the last part of this work some testcases are investigated and the improvement in the dynamics is shown. © (2006) by the Katholieke Universiteit Leuven Department of Mechanical Engineering All rights reserved.
