Eigenfrequency Analysis of a Free Cylinder
Application ID: 271
This model calculates the eigenfrequencies and mode shapes of an unconstrained cylinder in axisymmetry.
The model is taken from NAFEMS Free Vibration Benchmarks. The eigenfrequencies are compared with the values given in the benchmark report.
Three different physics interfaces are used: Solid Mechanics and Shell in 2D axisymmetry, and Solid Mechanics in 3D with cyclic symmetry boundary conditions.
In addition to the actual benchmark, it is shown how to also compute eigenmodes with a twisting deformation.
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 Tabella delle Funzionalità 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.
