You are invited to join us at COMSOL Day Wien for a day of minicourses, talks by invited speakers, and the opportunity to exchange ideas with other simulation specialists in the COMSOL community.
Presentation details will be published soon. Register for free today.
The COMSOL Multiphysics® software supports your R&D and engineering with realistic physics-based models and simulations. But did you know that it also contains many tools to facilitate your modeling process and functionality to help you advance beyond everyday modeling? In this minicourse, we we will discuss and demonstrate the functionality available in the Definitions node of the Model Builder. This node includes probes, functions, interpolations, integration techniques, component couplings, and more.
This introductory demonstration will show you the fundamental workflow of the COMSOL Multiphysics® modeling environment. We will cover all of the key modeling steps, including geometry creation, setting up physics, meshing, solving, and postprocessing.
NVH Methods for E-Mobility Development and Audio Acoustics
The upcoming market potential of electric vehicles (e-vehicles) suggests new directions for the noise, vibration, and harshness (NVH) development methods and strategies. In general, a dominant internal combustion engine (ICE) noise in the frequency range between 30 and 500 Hz is shifted toward higher frequencies in the kHz range, leaving behind an in-cabin noise decomposing with a mid-frequency gap. Customers might get discomforted by a nonbalanced background noise, and NVH engineers are struggling with reduced masking effects for standstill and low-speed conditions.
This talk will present results from selected feasibility studies, which contribute to e-vehicle acoustics. A multiphysics whining noise simulation of an e-motor power train gives insight into source characteristics and implies optimization potentials. The mid-frequency gap is suggested to be masked using a physical modeling approach of synthetic engine noise. Finally, potential directivity improvements of a personal zone audio integration within a headrest are shown.
