Noise, Vibration and Harshness (NVH) Analysis by American Engineering Group (AEG)

NVH analysis provides essential benefits towards designing vehicles for ride comfort and quietness, an increasingly competitive advantage in today's global automotive market. The design of a car body structure is decisive in order to gain favorable vibration and acoustic behavior of vehicles. The body structure is the most significant transfer path for road-excited and engine-excited vibrations. The body panel vibrations are then radiated into the vehicle cavity, where they are perceived as audible noise. Apart from the audible noise, which is transferred into the cavity, structural vibrations of the body are perceived as an annoyance as well.

AEG Product Design and engineering solutions have a dedicated and focused NVH team with core competency in solving complicated design problems pertaining to automotive and aerospace applications with HPC (High Performance Computing : SGI-Altix/16 GB RAM/1500 GB HDD/Msc.Nastran 2005 R2 DMP etc) resources. The NVH team comprises of experienced and skilled team members having automotive background in various engineering disciplines which help designers analyze the NVH attributes before the first vehicle prototype is built, allowing engineers to understand potential problems and identify solutions early in the design process.

AEG has engineering team with fully equipped engineering tech center in Bangalore, India who imparts necessary knowledge and experience during the product design and development process. Few of the capabilities include aero-acoustic analysis, exhaust system acoustic analysis, NVH optimization (body, chassis, brake, tire etc.), and transmission loss studies. In any vehicle NVH, testing plays a major role in optimizing the vehicle design for NVH. Our design experts have hands-on experience in Test plan preparations, Testing methods and techniques, Testing, Test data collection and analysis, Test-CAE correlation techniques, Design modifications based on testing etc.

Focused Engineering Solutions by AEG

By
Focused Engineering Solutions for the Manufacturing Supply Chain by American Engineering Group Computer-Aided Design, Engineering and Manufacturing (CAD/CAE/CAM) are tools that help reduce costs and shorten the design, prototype and production cycle. These computer-aided tools can also help to incorporate Six Sigma, Lean manufacturing and Just-In-Time (JIT) in the supplier processes bringing credibility to new design concepts. American Engineering Group (AEG) is utilizing these tools to provide a Multisourcing Manufacturing Solution (MMS) by bringing new automotive components to the marketplace in the shortest possible time, with the lowest cost, and highest quality. CAD/CAE/CAM are becoming more popular as a standard analysis tools in the automotive industry for design, failure and manufacturing process analyses. Another notable reason for this popularity is the recent changes in automotive specification requirement for parts comprised of new materials or designs. The automotive ind...

AEG Torsional Damper - brief description

By
American Engineering Group (AEG) has developed a new “Dual Torsional Damper System”. This new AEG system design will allow varying static properties and provide dynamic shock and vibration mitigation over a wide load range for automotive and industrial applications. This dual structure system provides both axial and radial damping. The torsional damper system will have two elastomer elements with top element functions as a vibration damping element and the bottom spherical elastomer element as a noise & harness damping element. AEG dual mode damper system includes a spherical soft viscous bushing hub designed for being rigidly connected to a drive shaft, and an inertia ring, connected to the hub by means of a thin Polyurethane material layer. This dual-layer elastomer damper system is designed for torsional vibration reduction of the crankshaft system on multi-cylinder engine for vehicles. AEG polyurethane torsional dampers are designed to provide significant reduction of sou...
