The OROS EV/HEV NVH Testing Solution is a complete system designed to address the unique noise, vibration, and harshness (NVH) challenges of electric and hybrid vehicles. It integrates advanced software for e-NVH analysis, high-end modular instrumentation for data acquisition, and specialized consulting and training services. Developed in cooperation with EOMYS, the solution supports the identification and resolution of electromagnetic and structural noise sources, enabling engineers to optimize vehicle acoustic comfort and performance. The software environment manages various electric motor topologies, pre-analyzes main excitations, and provides tools such as electric markers, spatiograms, and sound design modules. The system supports a wide range of NVH applications, including transfer path analysis, operating deflection shapes, modal analysis, sound power, sound quality, and source localization. The modular Teamwork instruments allow for scalable, distributed measurements, making the solution suitable for both laboratory and field testing.
