Experiencing the Benefit of Optimized Laminated Glass Interlayer Material Using a Driving Simulator for NVH

In this paper, we present the process we propose to evaluate the effect of the laminated glass interlayer material on the Noise, Vibration and Harshness (NVH) performance of vehicles. The process starts from lab measurements to evaluate the glass damping and sound transmission loss and demonstrate the benefit of using optimized interlayer material. The results are then used to develop filters to adapt a vehicle model created in a driving simulator for NVH. With this process, it is not necessary to physically install the windshield in the vehicle to be able to listen and experience the benefits of switching to an optimized interlayer material. We use results from a real application case to verify the validity of the process and we share in our conclusions the future direction for this work to make the process completely virtual by using CAE simulation data.
