Helmholtz resonators are used in exhaust systems, as they can attenuate a specific narrow frequency band. The presence of a flow in the system alters the acoustic properties of the resonator and the transmission loss of the subsystem. In this tutorial model, a Helmholtz resonator is ... Mehr lesen
Dieses Modell zeigt eine vollständige vibroakustische Analyse eines Lautsprechers einschließlich Treiber, Gehäuse und Ständer. Sie können eine nominale Antriebsspannung anlegen und den resultierenden Schalldruckpegel im Gehäuse und im Außenraum sowie die Verformung des Gehäuses und des ... Mehr lesen
Several mass–spring–damper models have been developed to study the response of a human body where mass, spring, and damper elements represent mass of different body parts, stiffness, and damping properties of various tissues. In this example, a lumped model of a human body having five ... Mehr lesen
A standing contact fatigue test is a procedure used for testing crack growth on the subsurface level. In such a test, a spherical object is pressed against the tested materials and cycled between a high and low compressive load. No translational movement between the two occurs. After a ... Mehr lesen
This app demonstrates the following: Using the knob form object Updating the geometry by rotating a knob Provides info if the results are above or below certain critical values Many trucks are equipped with cranes for handling loads and such cranes have a number of hydraulic ... Mehr lesen
This conceptual example shows how to calculate critical points in models with contact. The model consists of two contacting arches modeled with the Shell interface. The contact problem is solved using the penalty method. The upper arch is loaded with displacement controlled edge loads ... Mehr lesen
When a droplet is placed on a substrate on which surface acoustic waves (SAWs) are traveling, the energy of the SAWs is transferred into the droplet to form an acoustic field. The transferred energy is attenuated and generates a streaming flow. This type of streaming enables contactless ... Mehr lesen
This example studies the deformation of a hemispherical shell, where the loads cause significant geometric nonlinearity. The maximum deflections are more than two magnitudes larger than the thickness of the shell. The problem is a standard benchmark, used for testing shell formulations ... 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
This model shows how you can implement a user defined hyperelastic material, using the strain density energy function. The model used is a general Mooney–Rivlin hyperelastic material model defined by a polynomial. In this example, you will see two material models based on the defined ... Mehr lesen
