Nonlinear Ferromagnetic Diaphragm
Application ID: 144001
A magnetic diaphragm is a flexible, thin structure that interacts with magnetic fields to perform mechanical or sensing functions. When subjected to an external magnetic field, the diaphragm deforms due to magnetomechanical interactions, converting magnetic energy into mechanical displacement or, conversely, mechanical deformation into changes in the magnetic field distribution. In this model, you will study the magnetomechanics of a magnetic diaphragm using the Magnetomechanics, Shell multiphysics interface. This interface combines the Shell and Magnetic Fields physics with moving mesh functionality, allowing simulation of the coupled mechanical deformation and magnetic field interactions for thin, flexible structures.
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.
