Abstract
An apparatus and method for reducing displacement of a washing machine having a drum rotatable about an axis of rotation is disclosed. The washing machine comprises a chassis and a motor for rotation a drum. The drum is suspended from the chassis by a suspension. The suspension can comprise springs having six natural frequencies that can resonate at a rotational speed of the drum driven by the motor. The suspension system can be tuned such that resonant frequencies can be varied based upon rotational speed of the drum.
