Abstract:
Mechanisms are intensively used nowadays in the industry as well as in our daily life. Depending on their required static and dynamic properties, balancing is often necessary in order to increase their efficiency (reduced vibrations, wear, fatigue, noise) or to facilitate their use (simplified control, improved repeatability). While the most common types of balancing (static, force, moment and dynamic balancing) are well known, numerous other types of balancing exist, which have not been systematically classified in the literature. We will present a taxonomy of 16 types of balancing illustrated by elementary 1 DOF mechanisms exhibiting the corresponding dynamic properties. A generic 1 DOF reconfigurable demonstrator will be used to practically illustrate the phenomena. The concrete use of these theoretical concepts will then be shown by applying them to the design of a novel 2 DOF horological oscillator, for which balancing is essential.
Bio:
Hubert Schneegans obtained an engineering degree in mechatronics at INSA Strasbourg in 2018 and a master’s degree in image processing and robotics at Telecom Physique Strasbourg on the same year. He was the hired at Instant-Lab – IGM – EPFL where he worked for three years on flexure-based mechanisms dedicated to surgical instruments and horological oscillators. In April 2021 he started his PhD under the supervision of Prof. S. Henein. His research focuses on the balancing of mechanical horological oscillators.
