NVH and Vehicle Acoustics

Driving comfort and vehicle acoustics are playing an increasingly important role in vehicle development. On the one hand, the qualitative assessment of a vehicle is significantly influenced by its acoustic and vibration behavior; on the other hand, ever stricter noise emission limits apply worldwide with regard to noise protection.

In order to support the development of vehicles in this respect, NVH behavior must be taken into account in earlier phases of the product development process. In particular, the interactions between subsystems and the overall system, as well as their effect on humans, must be investigated and quantified.

We are therefore researching efficient methods and processes that realize a holistic and process-accompanying validation with regard to acoustics and vibrations.

RF NVH and Vehicle Acoustics

Research Focus:

Research focusses on methods and processes for the development and validation of user-oriented mobility systems. The focus is on the continuous integration of simulation and testing in the field of NVH, as well as the design of validation environments. The main topics are:

  • NVH (complete vehicle and components)
  • Comfort objectification, evaluation methods and validation of vehicle interior and exterior acoustics
  • Simulated pass-by: vehicle exterior noise homologation
  • Suggestive sound design: use of an active sound design to influence driving behaviour 
  • AVAS warning noises: objectification and prediction of the subjective perception of Acoustic Vehicle Alerting System (AVAS) warning noises
  • Vibroacoustic metamaterials (VAMM)
  • NVH behaviour of fuel cells

Systems

We research NVH methods and processes using both complete technical systems and selected subsystems. Power tools and drive systems are available to us directly at the Institute for this purpose. In cooperation with our partners, we also research a broad spectrum of different systems, ranging from the automotive industry and its suppliers to special machine construction. In the research field ‘NVH and vehicle acoustics’, the focus for development- & validation environments is on:

  • Manually controlled and (partially) automated vehicles
  • System "(automotive) powertrain"
    • Conventional drive systems
    • Electric, hybrid and power-split drive systems
  • Subsystems and components
    • Transmissions and transmission topologies
    • Auxiliary units (air conditioning compressor, cooling and lubricant pumps,...)
    • Comfort actuators (window lifters, electric parking brake, steering assistance,...)
    • Vibration damping systems
    • Clutch systems
    • Exhaust systems
  • Active Sound Design (ASD)
  • AVAS Sound Design

Methods

In the research field, development and validation methods are used and developed for the following key topics in the context of NVH, taking systemic influencing factors into account:

  • Development of needs-based products and associated validation environments focussing on NVH
  • Comfort objectification for different stakeholders
  • Analysis and consideration of customer needs of end users, Vehicle manufacturer & supplier (scaling)
  • Exterior noise homologation during simulated pass-by
  • Determination of the acoustic centre
  • Influencing driving behaviour via active sound design
  • Prediction of subjective perception (annoyance/pleasantness) of AVAS warning noises
  • Vibroacoustic simulations (FE)
  • Auralisation using XR applications
  • Use of the IPEK-XiL framework for end-to-end validation of technical systems
  • Use of NVH methods according to standards: Transfer path analyses, modal analyses, sound power measurements, pass-by measurements, ...

Processes

Based on the theory of NVH, we research and design development and validation processes for product development, for example:

  • Processes for analysing and optimising NVH behaviour
  • Processes for acoustic measurements inside and outside the vehicle (e.g. artificial head measurements, simulated pass-by)
  • Processes for sound design
  • Processes for objectifying comfort and subjective human perception
  • Processes for benchmarking and standardisation
  • Processes for conducting reproducible driving and chassis dynamometer tests

Equipment

Practical, theoretical and experimental investigations on our test benches or using mobile measurement technology:

  • Acoustic roller test bench: 2-axis driven roller test bench with vehicle-in-the-loop technology in semi-free-field space (lower cut-off frequency of 63Hz).
  • Driving robot (SAP 2000)
  • 3D laser scanning vibrometer (PSV 3D) for non-contact and non-reactive recording of 3-dimensional vibrations of surfaces
  • 3D sound intensity probe (LMS SoundBrush)
  • Artificial head, uni- and triaxial acceleration sensors, Free-field microphones, 40-channel front-end and AFT TORnado
  • Head Acoustics ArtemiS SUITE
  • Acoustic camera (HEAD VISOR)
  • IPEK driving simulator with force feedback pedal
  • Various test vehicles (conventional, hybrid, electric, AVAS sound design)
