218. "EDRIVE#1 - Multi-Physic Analysis Of Power Electronic Control Parameters In A Simulation Framework"

Salamone Nicolo

13/07/2023 10:40

Incorporating sound quality markers into optimization objectives is a new approach that aims to design more efficient and high-quality powertrains. In this paper, a digital framework, which combines different simulation environments, is proposed with the intent of investigating the influence of pulse width modulation strategies on vibroacoustic response and energy consumption of an electric...

219. "EDRIVE#2 - NVH optimization of electric motors: optimization under constraints and uncertainty"

Dupont Jean-Baptiste

The optimization methodology described in this paper aioms at minimizing the noise and vibrations of electric motors. It relies on a numerical workflow involving electromagnetic, dynamic and acoustic models. Afterwards, a deterministic optimization method is described and applied to automotive traction motors. A robust enhancement of the optimization is then presented. It aims at considering...

The geometrical limitations of microphone arrays as well as the unavailability of multiple channel data acquisition systems or their incurred costs fundamentally challenge the sound source identification in acoustic imaging. This can be solved by sequentially scanning the object of study with a moving array with or without fixed references and requires the sound field to be stationary. In...

221. "EDRIVE#4 - Virtual measurements for exterior vibroacoustic problems using experimental modal models"

Staiger Julian

"This paper explores the application of experimentally derived vibroacoustic state-space models in virtual sensor schemes. These models are obtained through Experimental modal analysis (EMA). The paper demonstrates how both in-band and out-of-band contributions can be integrated into a unified state-space model. Additionally, the study illustrates how various measurement types, such as...

222. "EDRIVE#5 - Resynchronization of sequential measurements using the Maximally-Coherent Reference technique"

Albezzawy Muhammad Nabil

13/07/2023 12:00

Remote sensing of a physical field generated by a small number of sources is limited by the size of the available array of sensors and by the array density. These limitations may lead to asynchronously measuring the field by sequentially moving a small prototype array around its facets, however at the cost of losing the phase information between every array position. Resynchronization using...
