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:
