Self-contact in rubber/foam components: rubber gasket



This example demonstrates the use of the single-surface contact capability available for two-dimensional large-sliding analysis. Components that deform and change their shape substantially can fold and have different parts of the surface come into contact with each other. In such cases it can be difficult to predict at the outset of the analysis where such contact may occur and, therefore, it can be difficult to define two independent surfaces to make up a contact pair.
This model is used to analyze an oil pan gasket, which enhances the sealing of the oil pan against the engine block. The primary objective is to reach or exceed a threshold value of contact pressure where oil will not leak at the gasket bead/cover/engine block interfaces.

Pressure penetration analysis of an air duct kiss seal

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.

AEG Torsional Damper - brief description

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 sound and …
