In this verification example, forced random vibrations of a simply-supported deep beam are studied. The beam is loaded by a distributed force with a uniform power spectral density (PSD). The output PSD is computed for the displacement and bending stress response. The computed values are ... Mehr lesen
The reliability of a bike frame can be estimated by analyzing the structural stress subjected to different load cases. This app leverages LiveLink™ for SOLIDWORKS® to interactively update the geometry while computing stress analyses. Using this app, you can easily test different ... Mehr lesen
In this example, the eigenmodes of a structural damper are computed. In the damper, most of the deformation is controlled by the viscoelastic domains, which have strongly frequency-dependent stiffness and damping properties. This leads to a nonlinear eigenfrequency problem, which can be ... Mehr lesen
As integrated circuit (IC) technology advances, with circuits becoming more powerful and compact, it is increasingly important to identify and prevent any cause of circuit failure. One particularly critical factor contributing to circuit failure is electromigration within the ... Mehr lesen
Laminated shells made of carbon fiber reinforced polymer (CRFP) are common in a large variety of applications due to their high strength-to-weight ratio. The widespread attention to laminated shells is due to their diverse applications in aerospace, marine, automotive, and various ... Mehr lesen
This example models heat generation in a beam-like structure subjected to small amplitude vibrations. The model computes the linear elastic response in the frequency domain. The transient heat-transfer analysis simulates the slow-rising temperature in the beam using the heat generated ... Mehr lesen
This model studies the natural frequencies of a pre-tensioned string using the 2D Wire interface. This is an example of “stress stiffening”; in fact the transverse stiffness of wire elements is directly proportional to the tensile force. Strings made of piano wire have an extremely high ...

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
This model illustrates how to perform prestressed eigenfrequency and frequency response analyses in a contact problem. A circular plate is squeezed between two thicker plates. The peak of the prestressed frequency response analysis is compared with the prestressed eigenfrequencies as ... Mehr lesen
This example demonstrates the use of the Solid-Beam Connection multiphysics coupling to create transitions between the Solid Mechanics and Beam interfaces. Two different connection types are discussed, and a comparison of the stress distributions at the transition is made. Mehr lesen
