Characterisation of system-level NVH performance
Characterisation of system-level NVH performance, based on componentlevel models & measurements.
Challenge
NVH (Noise, Vibration and Harshness) performance is a system-level property resulting from complex interactions between components such as tires, suspensions, gearboxes and machine structures. Today, NVH assessment still relies heavily on costly and time-consuming prototype testing and iterative redesign cycles.
Current Component Transfer Path Analysis (CTPA) methods already enable virtual assembly and NVH prediction, but important challenges remain:
- large and complex interfaces,
- non-discrete connections,
- acoustic transfer paths,
- hybrid experimental–numerical modelling,
- and measurement uncertainty under operational conditions.
Project goals
NVH-TPA_IRVA aims to develop advanced methodologies for virtual NVH prototyping based on reusable component-level models and measurements. The project focuses on:
- improved in-situ measurement techniques and test rig design,
- CTPA and hybrid TPA methods for large and complex interfaces,
- advanced equivalent source representations,
- and system-level validation on industrially relevant use cases.
The ultimate goal is to enable faster and more reliable system-level NVH prediction, reducing physical prototype iterations and accelerating machine and vehicle development.
