Bruel & Kjaer introduces Virtual Vehicle Simulators
09 May 2007
Virtual, in-car testing which allows automotive designers to experience first-hand the noise and vibration environment within vehicles – before they’ve even been created - has arrived with the launch of Bruel & Kjaer’s NVH Vehicle Simulator systems.
As a new component of the Bruel & Kjaer sound & vibration data acquisition and analysis platform - PULSE 11.2 - the NVH Vehicle Simulator consists of a computer, pedals, steering wheel and two additional screens, to be used with a PC on the desktop or installed into a vehicle for instant, accurate recreation of noise and vibration effects.
The Desktop NVH Simulator uses one screen to display a virtual road complete with bends, verges, single lane and even motorways. The second monitor allows users to select their vehicle specification, so they can experience the total sound of a vehicle or several vehicles, as perceived by the driver. Additionally, the “driver” can change individual factors (such as engine type, gearbox, exhaust, wind noise, etc), which all contribute to the vehicle’s total sound.
The Full Vehicle Simulator creates a live scenario using a real vehicle, with the simulator installed and placed in front of a large screen onto which virtual road situations are projected. A person can sit inside, ‘driving’ the car to assess the effects of sound and vibrations. The simulator responds immediately to the driver’s actions, reproducing the exact sound and vibrations for that particular vehicle’s structure as it would actually be experienced - when driven on the road - by different surfaces, the vehicle’s speed, engine speed and throttle position.
“Our PULSE NVH Vehicle Simulators are a key element in helping automotive customers reduce time into the marketplace,” said Torben G. Nielsen, Bruel & Kjaer Business Manager Automotive. “It allows them to experience the noise, vibration and harshness of a vehicle component, within a complete vehicle, in the correct context, so vital decisions can be made early in the development program before a physical prototype has been built.”
