Abstract
A method for reducing displacement of a wash basket that is rotatable about an axis of rotation within a washing machine. The method comprises the steps of: mounting a balancing ring to the basket in the plane that is generally perpendicular to a rotation axis of the basket. Another step is supporting the wash basket by a tuned suspension structure to the machine and determining two resonance critical frequencies for two translational degrees of freedom and three resonance rotational frequencies for the three rotational degrees of freedom of the suspension structure. The method also comprises the step of tuning the suspension structure so that the two critical frequencies of translation each occur at or below a critical first motor speed and so that the three rotational frequencies occur at a second speed that is above the critical rotation speed.
