When Silence Reveals Friction: Noise Vibration Harshness (NVH) Challenges in Electric Vehicles
The transition to electric vehicles (EVs) has fundamentally altered the landscape of Noise, Vibration, and Harshness (NVH) research. While internal combustion engines provided a broadband acoustic "mask" for secondary disturbances, the silence of EVs pushes previously negligible friction-induced vibrations to the forefront of passenger discomfort. This talk explores the shift toward multidisciplinary system-level modelling to tackle these emerging challenges, focusing on:
- Frictional coupling: analysing the interplay between tangential and normal vibrations at critical interfaces like brake pads and bearings;
- Active mitigation: advancing beyond passive damping toward active suspension and control systems to suppress electromagnetic and mechanical coupling;
- Holistic simulation: leveraging Multi-body Dynamics to integrate complex drivetrain interactions into a single, comprehensive analytical framework.
Prof. Adolfo Senatore is an Italian researcher in tribology, mechatronics, and mechanical vibrations. He obtained his Ph.D. in Tribology from the University of Pisa (2002) and is a full professor at the University of Salerno. His research focuses on friction modelling, lubrication, and vibration phenomena in automotive and mechanical systems. He has been author of around 250 papers among journal articles, conference papers, and book chapters. He was visiting scientist at Technical University of Berlin and visiting professor at Czech Technical University in Prague. He currently holds the position of Chief researcher at Vytautas Magnus University.
He also serves on editorial boards of several journals and he is Editor-in-Chief of Proceedings of the Institution of Mechanical Engineers, Part K: Journal of Multi-body Dynamics.
