Control and Optimization of Vibration and Noise for Powertrain of EV

With the rapid development of the electric vehicle (EV) industry, the architecture and operating conditions of the powertrain are undergoing profound changes. Vibration and noise (NVH) issues have become key factors affecting vehicle comfort, reliability, and market competitiveness. This special session focuses on the NVH characteristics of EV powertrains under electro-magnetic-mechanical multi-physics coupling conditions. It provides a platform for academic exchanges on cutting-edge topics including vibration and noise mechanisms of electric drive systems, noise control of gears and bearings, electromagnetic excitation and structural response, sound quality evaluation, and active control.

The session will bring together experts, scholars, engineers, technical professionals, and postgraduate students from fields such as automotive engineering, mechanical dynamics, electric machines and electrical engineering, acoustics, and testing technology. In-depth discussions will be held on key scientific and engineering issues, including vibration suppression of high-speed electric drive systems, multi-physics coupling modeling and simulation, source identification and transfer path analysis, lightweight design with NVH performance integration, active noise control (ANC), and semi-active mounting technology. Furthermore, the session will showcase the latest theoretical research achievements, experimental methods, and engineering application cases, analyze industry trends and technical bottlenecks, promote the deep integration of industry, academia, research, and application, facilitate the translation of academic innovations into engineering practice, and support the high-comfort, high-reliability, and sustainable development of China’s new energy vehicle industry.
