Over the last two years, our company developed at a remarkable pace: the DIRAC software is being used by most of our clients, we opened a new office in Munich, we are now serving clients globally and most of all, we are releasing (again) a brand new, highly innovative software application: SOURCE. With SOURCE, we can characterize vibration sources and use this to predict interior noise, while making small adjustments or using multiple vehicle variants – all in a single, intuitive application.
A new way of working
The automotive industry is making one of the largest transformations in history, with major challenges as electrification, autonomous driving and a global crisis on top of it. New components, such as refrigerant compressors for battery cooling or new powertrain concepts, are challenging to work with – especially when travel restrictions and supply chain disruptions force a different way of working. Both automotive OEMs and their suppliers need to re-evaluate existing R&D processes in favor of agility and costs.
We propose, with our VIBES methodology, a combined approach using computer simulations and physical testing using our Virtual Point Transformation technique; building hybrid models which use best of both worlds. Source Characterization using Blocked Forces allows suppliers and OEMs to work together and predict interior noise without physically mounting all components into a full prototype, and new ISO standards ensure compability across the industry.
The blocked force source characterization method (as part of the component-TPA approach) allows suppliers to measure actively vibrating components in their own facilities, while OEMs can make full-vehicle NVH predictions using this data.
