Recently, two graduate students from Automotive Engineering college attended the 2025 SAE International Conference in the United States to exchange research achievements in automotive noise and vibration control technology.
The SAE 2025 Noise and Vibration Conference and Exhibition, centered on vibration and noise control technologies in the new mobility era, was successfully held from May 12 to 15, 2025 in Grand Rapids, Michigan, USA. The event brought together over 300 participants from leading global automakers including General Motors, Ford and Tesla, renowned acoustic and vibration solution providers such as HEAD acoustics, Siemens and Analog Devices, as well as prestigious academic institutions like Purdue University, University of Kentucky and Politecnico di Torino. Representing our institution, graduate students Qian Yushu (Class of 2022) and Xiong Chenggang (Class of 2023) delivered academic presentations titled "Development of Offline Simulation Software for EV Active Sound Design" and "MLP-Based Sound Quality Evaluation Model for Vehicle Acceleration" respectively at the Noise and Vibration Control session, showcasing innovative achievements from their NVH team in the fields of sound quality evaluation and active sound design.
Mr. Qian Yushu's presentation on the hybrid electric vehicle active noise control system and battery electric vehicle active sound design technology attracted significant attention from international automakers. Meanwhile, Mr. Xiong Chenggang's proposed MLP model for evaluating vehicle acceleration sound quality - which employs machine learning to quantify acoustic performance - generated lively discussion among attendees for its potential to enhance user experience in new energy vehicle design through measurable sound quality improvements.
Upon returning to China, the two graduate students shared their conference experience and the cutting-edge international trends in NVH technology they acquired during an academic seminar held in the conference room of the college's Internal Combustion Engine Laboratory. Professor Liu Zhien, head of the college's NVH research team, commented that their participation not only demonstrated our institution's latest research achievements in NVH but also established valuable international collaborative bridges for the college.
Moving forward, the School of Automotive Engineering will continue to deepen international cooperation and exchanges, with particular focus on advancing China's new energy vehicle technologies in intelligent sound design and acoustic quality control.
