Fuel Cell Nanocomposite Double Lip Seal From American Engineering Group (AEG)

Nanocomposite double lip seal is a new nanotechnology based “over molded” seal for fuel cells from American Engineering Group , Akron, OH. This unique “double lip” seal has a primary and a secondary sealing surface. This EP terpolymer based elastomer formulation has a nano-blowing agent which helps to maintain high “long-term” sealing force retention in a fuel cell thermal cycling operational environment with vibration loads. This new nano technology based elastomer seal show very less “electrode poisoning” in fuel cell system. This sealing technology is adaptable to various planar fuel cell designs.

This acid resistant, high temperature stable over-molded plastic seal has a nano-blowing agent which activates in steam based curing. Compared to other elastomers, this nano-composite elastomer has excellent resistance to creep and fatigue with good flexibility and clear film. AEG’s proprietary steam post-curing protocol allow to extract all the un-reacted catalysts/monomers and also allow to activate nano-blowing agent in the EP terpolymer system. This seals has excellent chemical resistance with good UV and weather resistance. Low NBS smoke generation and high heat resistance with excellent dielectric strength.

AEG development engineers can help you to find a cost-effective fuel cell seal design based on this new seal technology. AEG has technology-driven design tools to provide optimum sealing on the customer fuel cell stack design using following analysis:

• “Volume fill” analysis

• Compression tolerance stack-up analysis

• Lateral tolerance stack-up analysis

• Design Failure Mode and Effects Analysis (DFMEA)

• Finite Element Analysis using a 3D CAD

Our Indian seal manufacturing facilities are ISO 9001/TS 16949 registered, and we constantly strive to improve customer satisfaction through the implementation of new seal technology with following quality/value improvement programs:

• Lean manufacturing/ Kaizen initiatives

• TQM studies

• Advance Product Quality Planning (APQP) studies

• Six Sigma scrap & cost reduction programs

This design was was presented in SAE World Congress 2007 .

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

Pressure penetration analysis of an air duct kiss seal

By
Seals are common structural components that often require design analyses. In this example, a nonlinear finite element analysis of seals is performed. Pressure penetration effects between the seal and the contacting surfaces are to be considered in these analyses, to make routine analyses of seals more realistic and accurate. Analyses of clutch seals, threaded connectors, car door seals and air duct kiss seals are some applications where pressure penetration effects are important. The surface-based pressure penetration capability is used to simulate pressure penetration between contacting surfaces.

Challenges in the Finite Element Analysis of Tire Design using ABAQUS

By
Finite Element Analysis of Vehicle and Tire has become a very important aspect of a tire design and failure analysis to most Tire companies. Tire modeling with ABAQUS is a very complicated process involving complex materials like hyperelastic rubber and textile reinforcements, large model size, prolonged simulation time and various convergence issues. This white paper intends to help in understanding the challenges in tire analysis and several tips and tricks that makes a difference in the quality of the results and processing time. AEG hopes that this article will be useful to ABAQUS users working in the field of tire design and analysis. A general tire has the following major tire components Tread Belt Region Inner Liner Sidewall Region Inner Carcass Region Bead Filler Region Apex/Chafer Region Beads Reinforcements Nylon Cap Ply Steel Belts Carcass Ply Constructing the structure of the tire and modeling of each component is the first step into the analysis.
