Acoustic and vibratory behaviour are key in the quality perception of the vehicle. Optimization of NVH (Noise, Vibration, and Harshness) in projects involve a deep understanding of the vibration behaviour of full vehicle and all its subsystems, including the acoustic cavity.
IDIADA has extensive experience in testing and simulating a variety of vehicles for the optimization of the NVH performance, with a deep understanding of the methods to obtain a good correlation between simulation and reality.
By coupling finite element with Multi Body Models, we can accurately determine accelerations or Sound Pressure levels at specific points affected by suspension forces. Those models in combination with our Virtual Proving Ground allow the evaluation in a realistic environment of the full vehicle response during the development process.
NVH disciplines also encompass other systems' optimization like brake squeal simulation, squeak, and rattle of trimmings or aeroacoustics of side mirrors.
