This session provides a good overview of recent innovations to modeling and visualization techniques, tools, and methodology, both analytical and experimental involved in identifying, calculating and modifying various noise and vibration sources and paths in vehicles, aircraft and various consumer products and assist in the design and validation of noise and vibration targets. Also included are Whole Body and Hand Arm Vibration experienced by drivers as well as acoustical design factors of audio, infotainment, and hands free devices.
This session is focused on base engine, mounts, accessories, fuel injection system, combustion system, turbo chargers, EGR system, transmission related design or development noise and vibration topics. With the advent of GDI engines- the performance vs. NVH relationship has become more interesting and challenging. The focus of this session is to share experiences on analyzing, testing, and developing solutions to structural noise and vibration problems from powertrain sources.
This session discusses the noise sources, noise signatures, noise control strategy, and NVH technology unique to electric and hybrid powered vehicles. It is intended to bring a greater awareness of the NVH characteristics of these new vehicles to all NVH practitioners. At the same time, it will provide a forum so that advances in power systems, drive trains, batteries, and energy storage can be addressed with appropriate NVH technology as needed.
This session covers noise and vibration in heavy trucks and buses and all other off-road vehicles. Special attention will be focused on the noise and vibration problems found in these vehicles, as opposed to passenger cars and light trucks, and to the engineering solutions required to solve these problems. Included in the session are discussions of special measurement methods, modeling specifically directed to these vehicles, and NVH materials with special properties to address unique problems.
This session is looking for manuscripts that focus on analyzing, testing, and developing solutions to minimize the noise and vibration from braking systems. Tools that can be discussed include but are not limited to analytical modeling, experimental testing and predictive correlation. New techniques for the design of brake systems to prevent noise issues are of particular interest.
This session is searching for manuscripts on both numerical and experimental work pertaining to noise caused by air flow around vehicles or stationary machines. Potential topics could include: flow-induced interior noise, flow over protrusions, sunroofs, windows, cooling fan noise, or flow noise in exhaust or intake systems.
This session is focused on the vehicle body interior noise issues caused by friction and/or impact due to the vibration of interfacing components. The papers in this session will investigate those issues through the best practice of analytical and experimental applications.
