Walking Instability in a Washing Machine
Application ID: 19901
Walking instability, due to non-uniform distribution of clothes, is a common problem in lightweight portable washing machines. This problem is more severe in horizontal-axis washing machines, which are more popular because of their high efficiency in spite of high manufacturing cost.
This model simulates a simplified model of a horizontal-axis portable washing machine and predicts the verge of walking instability during the spinning cycle. A control-based active balancing method is also implemented to eliminate the instability and vibrations present in the system.
This model example illustrates applications of this type that would nominally be built using the following products:Multibody Dynamics Module
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.
