NVH Highlights and (Pot)Holes 1972-2001 2003-01-1517
The NVH performance of motor vehicles has been improved dramatically during the 1972-2001 period. The paper identifies the main advances made, i.e. the development highlights and indicates a number of points where a lot of work still needs to be done (Holes or with and automotive flavor “Potholes”).
The paper is structured as indicated below.
Engine efficiency and vibration isolation
Noise Control proper
Passby noise treatment and Aerodynamics
Interior treatment simulation and optimization
Noise Control material improvements
Dissipative treatment packages
Noise Quality engineering
Development Methodology: Benchmarking
Modeling car subsystems
Optimization; application to ever-larger subsystems
