The purpose of this session is to describe solutions for weight savings, which is a well-known strategy for improving fuel consumption in vehicles, and to explain the NVH impact of these weight reductions. Weight savings can come from interior and structural parts of vehicle in the form of one of the following solutions: composite materials, light weight alloys, aluminum & magnesium versus steel, bonding dissimilar materials, new damping compounds, elimination of mass barriers, higher performance acoustical products, reduction of part weight, reduction of part size, material substitutions, or reduced complexity of parts. NVH countermeasures for these weight reduction solutions will be outlined so that lightweight design for next generation vehicles can be implemented with attention to noise and vibration throughout the vehicle.

This workshop will present a practical introduction to SEA Modeling and its use in vehicle applications. A brief introduction to SEA will be followed by a broad spectrum of SEA models applied to vehicle acoustic design. Three distinct applications will be presented. These applications extend from passenger vehicle and heavy truck to SEA applied to aerospace vehicles. This workshop is structured as an introduction to SEA especially for those with limited experience in vehicle acoustics modeling. It also provides an opportunity to establish technical contacts for continuing working relationships.

The purpose and orientation are to empower engineers to recognize and fully connect their innate hearing capabilities with interactive analytic tools to characterize, design and improve mobility-product sounds considering human perception. An overview differentiates sound quality engineering from general acoustics as historically practiced, introduces the scientific field of Soundscaping (merging rapidly with SQ engineering and being applied to automotive development*) and provides a thought-context for straightforward, productive work. Examples are given regarding how to approach issues, and about human perception and connecting it with technical measurements including both conventional and psychoacoustic tools. The sequence of practical topics, examples and methods includes hardware issues such as sound card behavior, and time data resolution 24 bits, 16 bits and implications.

The basics of muffler and silencer design and analysis will be reviewed. Application cases will be shown including a cross-flow type muffler another containing an after-treatment device. 1D plane wave and 3D boundary element simulation will be demonstrated in each case. In addition, the two-load method will be used to determine the transmission loss for the cross-flow muffler. Following this, the effect of flow and source impedance will be discussed.

Please join us for the 10th Anniversary of the Structure Borne NVH Workshop. Since the beginning, the workshop has stressed the fundamentals of source-path-receiver principles. A theoretical foundation covers the basics of low-frequency NVH ( to 100 Hz where NVH is felt) and mid-frequency (to 500 Hz were NVH is heard). The application topic will discuss the causes of NVH variability and corresponding new methods of simulation to assure robustness.

Frequency analysis is often referred to as Fourier analysis but is that really true? The foundation is based on stationary and "Fourier signals." What happens if that is not the case? Modern FFT signal analyzers use very sparse sampling that is correct according to Shannon but what will happen when using time domain analysis. Many of the myths and frequent questions will be answered using a "user perspective" and rules of thumb will be given together with good methods to avoid large errors. After attending this session, a much better understanding in regards to pitfalls and proper methodology will be the outcome.

The vehicle-terrain interaction in an off-road environment creates unique challenges for designers of both wheeled and tracked off-road vehicles. Not only should vehicle designers have a working knowledge of the fundamentals of on-road vehicle dynamics, they should also have the specialized knowledge of the vehicle dynamic characteristics found in construction, agriculture, and military off-road vehicles. This one-day seminar concentrates on the basics of off-highway trucks and the differences with their on-highway counterparts.

One of the most important safety critical components on cars, trucks, and aircraft is the pneumatic tire. Vehicle tires primarily control stopping distances on wet and dry roads or runways and strongly influence over-steer/under-steer behavior in handling maneuvers of cars and trucks. The inflated tire-wheel assembly also acts as a pressure vessel that releases a large amount of energy when catastrophically deflated. The tire can also serve as a fulcrum, both directly and indirectly, in contributing to vehicle rollover. This seminar covers these facets of tire safety phenomena.

The principal functions of the pneumatic tire are to generate driving, braking, and cornering forces while safely carrying the vehicle load and providing adequate levels of ride comfort. This seminar explains how tire forces and moments are generated under different operating and service conditions and, in turn, demonstrates how these forces and moments influence various vehicle responses such as braking, handling, ride, and high-speed performance. The content focuses on the fundamentals of tire behavior in automobiles, trucks, and farm tractors, but also includes experimental and empirical results, when necessary.
