Collaboration with Vehicle Designers for NVH goals

It is a must-have criterion among Domain Experts, vehicle integration Team and NVH Dept. that they collaborate with each other before sign off for production

Otherwise, a quiet vehicle may suffer from serious durability issues or lack of power and will not be launched at all and on the other hand, a powerful & durable vehicle may prove to cause a great discomfort to the vehicle passengers !

A below Table mentions challenges of 3 critical aggregates usually faced before final sign off ICE powered vehicles to meet the NVH targets!

Above list is not exhaustive

There are many such criticalities related to chassis, body trims, sealing, acoustic insulation, cooling Fan, exhaust, intake systems, etc.

Unless designers+ suppliers + experts in the domains of Engines, Transmission, Rubber Technology, Manufacturing, etc. come together, NVH Managers alone can not deliver the desired product.

A below Interaction model among various stake-holders, thus. truly represent a compromising position of NVH refinement of a vehicle

But if there is a Will (by Top Management), there will be a Way (to expand the NVH refinement area)!
