Eigenmodes of a Viscoelastic Structural Damper
Application ID: 75931
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 must be solved by iteration for each individual eigenmode. The procedure is automated through the use of model methods.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
