Siemens Digital Industries Software introduced system NVH prediction, a new Simcenter software application that can bring the benefits of a comprehensive digital twin approach to accurately and easily predict the interior and exterior Noise, Vibration, and Harshness (NVH) performance of a vehicle before a physical prototype is available for any type of vehicle: hybrid, fully electric, or internal combustion engine (ICE). This new Simcenter application helps engineers front load full vehicle NVH analysis and detect potential component NVH performance issues earlier by using measured and simulated component models to build a virtual prototype assembly. Simcenter is part of Xcelerator, Siemens’ integrated portfolio of software, services, and application development platform.
Simcenter uses a systems-engineering approach to enable the rapid creation of multiple vehicle variants. System-level component models based on test and/or simulation data are created by NVH experts and published to a library. These take advantage of the latest technology, such as component-based transfer path analysis, which allows engineers to characterize the NVH sources independently from the final receiver, to ensure that they are validated, scalable and reliable.
These validated components can then be rapidly assembled by non-NVH experts to represent a new variant and performance assessment can begin, reducing set-up times to a matter of minutes. This systems-based approach allows rapid reuse of available data and expertise by a much wider community of users within an organization. By enabling non experts to conduct performance prediction studies, it facilitates NVH performance assessments to be carried out at all stages of vehicle development.
