Sound & Vibration engineering in electric vehicle development
VIBES is a renowned expert in sound & vibration engineering for the automotive industry (the industry term is ‘NVH’, Noise and Vibration Harshness), and typically works with premium automotive OEMs in Europe, the US and Asia . VIBES uses an innovative methodology where test-data and computer models are combined in the NVH engineering process, which is especially relevant for electric vehicles. Electric vehicles lack the masking effects of a combustion engine and require a different engineering approach. The fact that Lightyear, as a young and innovative OEM, is not bound by restrictive historical processes intended for combustion-engine development, makes it an ideal partner for the VIBES way-of-working.
The focus of this collaboration is vibration source characterization: a process where measurement-data is converted to a model of the vibration source. This model is then used to optimize the full-vehicle NVH of the Lightyear One. The Lightyear One has several advanced components, such as the in-wheel electric engine, which are difficult to optimize using traditional NVH methods. VIBES will work together with Lightyear on these challenging components and distill the learnings into a software application to manage the process in the future. VIBES and Lightyear are both excited about this collaboration, which is also made possible by the province of South Holland.
