Project Description: The project aims to develop innovative calculation models to predict the noise and vibrations of gears with extreme precision. Thanks to these models, it will be possible to improve the design process and introduce optimization phases to improve performance and increase durability.

Objectives: This research project will make progress in the field of gear design as it proposes the development of innovative simulation models based on the Multibody Dynamics methodology. Thanks to this approach, it will be possible to identify noise and vibrations produced due to the deformation of the teeth. The fundamental concepts of the proposed simulation approach are essentially two: introducing the flexibility contributions of the gears; create contact-based models. Thanks to combining these key concepts, it will be possible to obtain results that have not yet been achieved. Therefore, it will be possible to identify and predict complex phenomena that occur in gear transmission systems, such as transients, gear changes, non-linear dynamics phenomena, noise, play, and impacts at high speeds. In the current state of the art, these types of phenomena cannot be evaluated within a single simulation environment. Generally, this involves difficulties in the optimization of the project.
