Ford Motor Company have been working with Brüel & Kjær Sound & Vibration‘s NVH simulator products for a number of years.

Automotive customers are increasingly demanding the provision of an integrated solution, combining hardware, software and services.

Ford utilise Desktop Simulators (DTS) to help refine their NVH targets and troubleshoot sound quality issues. The DTS allows Ford to evaluate standard NVH test or computer-aided engineering data in a true driving environment, converting the data in real-time into an accurate representation of the sound in response to the driver‘s inputs to the controls.

The limitation of the DTS is that it only handles the sound of the vehicle, not the vibration. There are many NVH phenomena where the total perception of the issue is a combination of the sound and vibration experienced by the driver or passenger, for example vibrations felt through the steering column and seat.

Ford evaluated a prototype of a Full-Vehicle Simulator (FVS) at Brüel & Kjær Sound & Vibration‘s Engineering Services facility at Millbrook and realised this was the next step in producing a more immersive experience for NVH evaluation. Ford took delivery of their FVS in December and have begun exploring the capabilities of the new system with the goal of integrating it into their product development processes.

“We realised that the FVS added the missing dimension of vibration and took us to the next level in improving NVH assessment and better decision-making. It requires a significant investment in resources but the benefits to our NVH development make it worthwhile" said Mark Stickler, Ford‘s Manager for Powertrain NVH.
