Abstract: Gear transmissions are widely used in several industrial applications. They have a lot of advantages such us compactness, ability to transmit high torques, efficiency … However, noise and vibration remain a major concern for this kind of transmission. In order to understand and then control dynamic behavior of gears, one can use experimental based approach which can be expensive and may not provide parametric case studies. Modeling based approach is an interesting approach allowing studying many operating conditions and is able to reproduce real object behavior.
This presentation will be focused on this approach. First, basics of gear modeling will presented. Then, special cases of complex gearboxes, like planetary and multistage ones, will be investigated taking into account several operating conditions with fluctuation of load and speed. Case studies will be presented and comparison between experimental results and simulation will be done.
