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

Vehicle/Tire/Road Dynamics: Handling, Ride, and NVH presents the connection between NVH and conventional vehicle dynamics where both tire and road play a key role. In this book, there is a chapter for handling dynamics that provides an introduction to ride dynamics and a chapter for ride dynamics that provides an introduction to NVH, presenting better coherence and synergy between these major areas of vehicle/tire dynamics. Accompanying the fundamental theories, case studies are given to facilitate comprehension. In addition to the experimental implementations, the state-of-the-art approaches to simulating vehicle/tire dynamics are presented from the viewpoint of both industry and academia. This new book bridges the gap for experts in tire or pavement NVH (also tire-pavement interaction noise) and those who are experts in vehicle dynamics. Conventional vehicle dynamics (e.g., handling/braking/cornering) is focused on low-frequency performance while NVH (noise/vibration/harshness) is focused on high-frequency performance. There is also another area called "ride" (comfort/stability) which focuses on mid-frequency. Presents a closed loop system for vehicle dynamics, covering handling, riden and NVH. Provides insights into how intelligent tires will enhance autonomous vehicle control and optimize multiple performances, especially for electric vehicles. Demonstrates how pavement characteristics could greatly influence vehicle handling/ride/NVH and improve/balance these performances.

A study was conducted by the Arizona Department of Transportation to evaluate the potential noise reduction benefits of using Asphalt Rubber Asphalt Concrete Friction Course (ARACFC) as an overlay for Portland Cement Concrete Pavements (PCCP). Comparative noise measurements were performed on several ARACFC and PCCP freeway segments. Third-octave frequency measurements were also performed to compare the frequency content of the noise generated by the two pavement types. Two separate measurement techniques were used to collect noise data. First, roadside traffic noise measurements were performed on adjoining freeway segments that consisted of different pavement types. For these measurements, two noise meters were positioned at equal distances from the adjoining freeway segments, and roadside traffic noise levels were measured simultaneously. The second measurement technique consisted of on-road tire-pavement noise measurements. For these measurements, a specially made bracket was clamped to the frame of a test vehicle, and a noise meter microphone was secured near the tire-pavement contact area. Noise readings were recorded as the test vehicle traveled at highway speeds over various pavement surfaces. Noise frequency data were collected using both measurement techniques.

Ihrer Arbeit in der Originalsprache: This work aims at identifying relevant road surface characteristics to mitigate tire-road noise of free-rolling tires using a systematic approach. As using open porous roads is already known as an efficient measure to reduce tire rolling noise, this study will focus on compact road surfaces which have a low acoustic absorption. Measurements on standardized ISO 10844 test tracks and on public roads are used to study the norm's representativity and its completeness.

Two of the most acclaimed reference works in the area of acoustics in recent years have been our Encyclopedia of Acoustics, 4 Volume set and the Handbook of Acoustics spin-off. These works, edited by Malcolm Crocker, positioned Wiley as a major player in the acoustics reference market. With our recently published revision of Beranek & Ver's Noise and Vibration Control Engineering, Wiley is a highly respected name in the acoustics business. Crocker's new handbook covers an area of great importance to engineers and designers. Noise and vibration control is one largest areas of application of the acoustics topics covered in the successful encyclopedia and handbook. It is also an area that has been under-published in recent years. Crocker has positioned this reference to cover the gamut of topics while focusing more on the applications to industrial needs. In this way the book will become the best single source of need-to-know information for the professional markets.
