Siemens Launches Automated NVH Solution

Siemens has announced a new automated software and hardware solution designed to help engineers identify the noise and vibration characteristics of mechanical components within hours instead of days. Siemens’ new automated component model extraction solution automates the extraction of locked forces in accordance with ISO 20270, enabling more accurate system-level NVH predictions through virtual prototyping.

Typically, characterizing components is both time-consuming and manual, relying heavily on the expertise of specialists. Engineers can spend days collecting measurements with limited repeatability, introducing variability into simulations and subsequent system integration. The new automated component model extraction solution addresses these challenges by automating both measurement and processing within a controlled, operator-independent workflow.

Developed in collaboration with Bosch, the solution uses Bosch’s patented predictive VIA technology, which Siemens provides as a unique, industrialized, and scalable implementation. By combining automated test benches with specialized software, it produces high-quality, simulation-ready component models that can be reused across multiple system variants.

“Automated component model extraction provides the speed, accuracy, and consistency needed to industrialize locked-force testing,” said Christian Sperrle, director of product management for the Vehicle Motion division at Bosch USA. “By enabling automated and repeatable measurements at test facilities around the world, it provides suppliers and original equipment manufacturers (OEMs) with a common database for digital NVH engineering. The result is faster decision-making, more reliable virtual development, and a cost-effective way to conduct large-scale locked-force testing, regardless of individual user expertise.”

By eliminating manual variability, automated component model extraction reduces FRF measurement time by 93% compared with conventional methods, while delivering 100% accuracy and repeatability across component variants. This repeatable database enables earlier and more reliable Digital Twin-based system validation, reducing reliance on physical prototypes and accelerating time to market.

Siemens’ new automated component model extraction solution is part of Simcenter’s physical testing portfolio, which includes Simcenter™ Testlab™ software, Simcenter™ SCADAS™ hardware, and Simcenter™ for Qsources™ hardware. The solution supports test-based and CAE-based component representations for applications such as electric motors, pumps, compressors, steering systems, and actuators, enabling virtual system integration.
