NVH Challenges of Vehicle Lightweighting

2021-06-14
The purpose of this session is to describe solutions for weight savings and to explain the NVH impact of these weight reductions. Weight savings can come from interior and structural parts of vehicle through various solutions of material selection to new dampening compounds. NVH countermeasures for these weight reduction solutions will be outlined so that lightweight design for next generation vehicles can be implemented with attention to noise and vibration throughout the vehicle.
