This model demonstrates how to use the Interior Contact feature to model the contact pressure at a bolted joint connecting two copper busbars. The AC current flowing through the assembly is induced to flow close to the outside boundaries of the conductors, but the contact resistance is ... Mehr lesen
This small tutorial model shows how to set up a model with a solid mechanics and a pressure acoustics domain including a common perfectly matched layer (PML). The PML is used to model an open or infinite domain for both the elastic waves and the pressure waves. Three configurations of ... Mehr lesen
Interference fit is a technique used to join or fit one part over or around another part. The internal part is cooled, so that it shrinks, and is then fitted. Once the part heats up again and expands, a contact pressure builds up at the interface between the two parts. This type of ... Mehr lesen
Die forming is a widespread sheet metal forming manufacturing process. The workpiece, usually a metal sheet, is permanently reshaped around a die through plastic deformation by forming and drawing processes. Simulations can be carried out in order to avoid cracks, tears, wrinkles, too ... Mehr lesen
In this tutorial the geometry of an occluded ear-canal simulator is optimized to match the acoustic response of a given ear. The target data in this model stems from a simulation of an ear canal, but it can also be based on measurements, or a response specified by a standard. Mehr lesen
Underground train grids span large areas under London, Paris, New York, and other cities. The building regulations require strict noise standards, and failure to comply could result in significant losses in the market prices of developments. Therefore, train-induced noise has to be ... Mehr lesen
Cross-coupled forces present in a hydrodynamic bearing often act as a negative damping in a rotor. Near the critical speed, this may lead to uncontrolled vibration of the turbocharger causing a risk of bearing failure. In this example, the influence of the cross-coupling forces on the ...

Berechnen Sie in diesem Modell die Ausbreitungsmoden in der Kammer eines Autoschalldämpfers. Die Geometrie ist ein Querschnitt der Kammer im Beispiel Absorptionsschalldämpfer. Der Zweck des Modells besteht darin, die Form der sich ausbreitenden Moden zu untersuchen und ihre ... Mehr lesen
This is a model of a simple photoacoustic (or optoacoustic) resonator. A pulsating laser heats a gas causing expansion and contraction and thus creates pressure waves. Such devices are used as sensors for measuring material parameters of the gas inside the resonator. The resonance ... Mehr lesen
In this example, the natural frequencies of a double hat beam are studied. The beam is made of two thin steel plates, joined together by spot welds along the flanges. The Spot Welds feature sets up multiple mesh-independent connections between the shells. Mehr lesen
