Title: NVH Highlights and (Pot)Holes 1972-2001
text: 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. 1 Introduction 2 Highlights 2.1 Vehicle 2.1.1 Body rigidity 2.1.2 Body leakage 2.1.3 Engine efficiency and vibration isolation 2.1.4 Suspension systems 2.2 Noise Control proper 2.2.1 Passby noise treatment and Aerodynamics 2.2.2 Interior treatment simulation and optimization 2.2.3 Noise Control material improvements 2.2.4 Multi-functional parts 2.2.5 Dissipative treatment packages 2.2.6 Noise Quality engineering 2.2.7 Development Methodology: Benchmarking 3 (Pot)Holes 3.1 Modeling car subsystems 3.2 Optimization; application to ever-larger subsystems 3.3 Simulation and Optimization of Passby Noise 3.4 Diagnostics 3.5 Materials and Shapes 3.6 Understanding the vehicle development process
