BRUEL & KJAER ANNOUNCES NVH
Bruel & Kjaer Sound & Vibration Measurement A/S has
signed an exclusive contract with NoViSim Ltd of Millbrook,
Bedfordshire to jointly complete the ongoing development
of the next generation of NVH Simulator products to be
sold and supported by Bruel & Kjaer as integrated tools
in the Bruel & Kjaer PULSE Data Acquisition platform which
is the Number One Windows®-based NVH test platform.
PULSE systems are scalable from one to more than 200 channels
with a full range of options and applications. PULSE front-ends can
be stacked to raise channel counts or used separately to gain flexibility,
measure from DC up to 200kHz, run multiple analyses (such as FFT,
Order and1/n-octave) in parallel, and in real-time, or use Bruel & Kjaers
advanced data-handling tools to analyse recorded time data.
The NVH Simulator represents an engineering tool that accurately
recreates the noise and vibration of a vehicle in a user interactive
environment. The NVH Simulator consists of a complete vehicle
situated in front of a projection screen, on which a virtual visual
scenario is projected. The user sits in the vehicle and experiences
the sounds and vibrations of the car being assessed as they drive
the vehicle through the virtual scenario. The simulator responds to
the drivers input by synthesising and reproducing the correct sound
and vibration for the instantaneous vehicle parameters, which are
presented in conjunction with a representative visual scenario.
As in a real vehicle, the stimuli are affected by changes in road surface,
vehicle speed, engine speed and throttle position.
The NVH Simulator is a key element in helping automotive customers
reduce time to market by allowing them to experience the NVH of a
vehicle component in a complete vehicle in the correct context, says
Torben G Nielsen, Bruel & Kjaers Business Manager Automotive, so
critical decisions can be made early in the development programme
before any physical prototype has been built.
Bruel & Kjaer is a world-leading manufacturer and supplier of sound
and vibration solutions. The company has more than 60 years of
experience in a wide range of applications for the automotive,
aerospace, industrial and environmental markets.
NoViSim Ltd was recently formed to produce NVH Simulator products,
based on the knowledge and experience of the founding partner
companies, Sound & Vibration Technology Ltd, VRtainment and
Triton Audio Solutions, a partnership with consulting and software
development expertise in advanced NVH, driving simulators and
audio signal processing. These products will be fully integrated into
the NVH processes of todays and tomorrows automotive industry.
