Book Description
A new close proximity (NCPX) method has been proposed and applied for the tire-road noise characterization of highway traffic. The implementation of NCPX is based on a set of surface microphones that is attached to a vehicle to directly measure the tire noise. To consider a combined effect of vehicle and road factors, a comprehensive field test has been performed with seven vehicle types at nine pavement sections of the test road. Testing parameters also include a vehicle speed ranging from 50 to 120 km/h, and two driving modes are applied at each speed: coasting and steady. It is found that asphalt pavements are quieter than all concrete pavements irrespective of testing conditions. Among concrete pavements, an 18-mm longitudinally-tined surface exhibits the quietest noise level, while a random transversely-tined surface is ineffective in minimizing the tire noise. Finally, the effect of a heavy axle load on the tire/noise generation is discussed.

Book Description
Automotive Tire Noise and Vibrations: Analysis, Measurement and Simulation presents the latest generation mechanisms of tire/road noise. The book focuses not only on tire/road noise issues from the tire/road structures, materials and dynamics, but also from a whole vehicle system. The analyses cover finite element modeling, mathematical simulations and experimental tests, including works done to mitigate noise. This book provides a summary of tire noise and vibration research, with a focus on new simulation and measurement techniques. Covers new measurements techniques and simulation strategies that are critical in accurately assessing tire noise and vibration Provides recent simulation progress and findings of CAE on analysis of generation mechanisms of the tire/road noise Features a Statistical Energy Analysis (SEA) and model of a multilayer trim to enhance the sound absorption of tire/road noise
