This tutorial example shows how to perform a random vibration analysis of a structure using power spectral density (PSD). The computations are based on the modal reduced order model (ROM). 詳細を見る

This tutorial application demonstrates how to model a hinge joint between two bodies in COMSOL Multiphysics. It also demonstrates various features available for joints, including Constraints, Locking, Spring, Damper, Prescribed Motion, and Friction. Many real structures can be ... 詳細を見る

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 ... 詳細を見る

Model of the sound radiation from a circular duct with uniform flow. The convected acoustic problem is described using the linearized potential flow equations, solved in the frequency domain. The acoustic inlet is treated including higher order modes using the Port boundary condition and ... 詳細を見る

This example illustrates the modeling of a sequential manual transmission, where the gears are selected sequentially with the help of a rotating drum. The shift drum has two grooves of specific profile carved around the circumference. As the drum rotates, the grooves on the drum guide a ... 詳細を見る

This tutorial model shows how to model a structure using both shell and solid elements, and how to create the transition between them. Results are compared between the shell solution and the full 3D solution, and the effects of the transition are highlighted. 詳細を見る

This model demonstrates alternative implementations used for describing a thin layer and the impact of the choice on the continuity of the displacement and stress fields. It is shown how a perfect interface can be obtained by asymptotically changing the material parameters. 詳細を見る

In this tutorial model, it is demonstrated how to incorporate a localized nonlinearity in a submodel. In this case, an initial elastic analysis reveals that a small region of a structure has stresses above the yield limit. To improve the results, an elastoplastic material model is added ... 詳細を見る

A plane-wave mode feeds an axisymmetric horn radiating from an infinite baffle toward an open half space. The radius of the waveguide attached to the horn throat is assumed to be fixed, as well as the depth of the horn and the size of the horn mouth attached to the baffle. By varying the ... 詳細を見る

This conceptual example shows how to handle a transient contact problem with stick-slip friction transition. A soft hollow pipe subjected to gravity is released at the top of a halfpipe. The pipe motion varies between sliding and rolling, depending on its position in the halfpipe and its ... 詳細を見る
