Elaphe motors are gaining recognition for their outstanding noise, vibration, and harshness (NVH) characteristics, which are crucial for complying with EU regulations. A workflow for optimizing acoustic noise maps was developed, improving motor noise levels by 20-60 dB.
Start date: 01/11/2015
Duration in months: 18
Problem Description
Elaphe motors must excel in noise, vibration, and harshness (NVH) design to gain visibility and recognition, comply with EU regulations, and reduce production costs for their unsprung electric in-wheel propulsion technology.
Goals
New services
Challenges
Complying with EU regulation No. 540/2014 is crucial for optimizing noise, vibration, and harshness (NVH) characteristics in design processes.
Innovation results
The experiment developed a workflow for optimizing and automating multiphysics computations of acoustic noise maps of in-wheel motors. The methodology, utilizing Cloud-based HPC, was tested on Elaphe M700 and L1500 in-wheel motors, resulting in a significant improvement in noise levels.
Business impact
HPC reduced simulation time and improved results, reducing development cycles and enabling more complex simulations. Elaphe's optimized workflow saves €120-€150k per year. The optimized design will increase sales by 20% and lead to additional revenue for up to €10k per year.
