Vibration in a Washing Machine Assembly
Application ID: 19957
Vibration and noise caused by the nonuniform distribution of clothes in the drum are common problems in washing machines and are important considerations in their design and optimization.
This model simulates a horizontal-axis portable washing machine using the Multibody Dynamics interface. An eigenfrequency analysis is performed to compute the natural frequencies and mode shapes of the entire assembly. A transient analysis is performed to analyze the vibrations induced in the housing during the spin cycle. The housing is modeled as a flexible shell.
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.
