    • 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.
    • 一种用于减少可在洗衣机内围绕旋转轴线旋转的洗涤筐的位移的方法。 该方法包括以下步骤:将平衡环安装在大体上垂直于筐的旋转轴线的平面中的筐中。 另一个步骤是通过调谐的悬挂结构将机器支撑在洗衣机上,并为悬架结构的三个旋转自由度确定两个平移自由度和三个共振旋转频率的两个共振临界频率。 该方法还包括调整悬架结构的步骤,使得平移的两个临界频率均出现在关键的第一电动机速度或低于关键的第一电动机速度,并且使得三个旋转频率以高于临界转速的第二速度出现。
