Minimizing load to the floor while spinning of drum type washer was studied. The outer tub of drum type washer supporting rotational drum is supported by vibration isolation structure, with a pair of dampers, springs, and rubber bushes. Using RecurDyn, amplitude of drum vibration and load to the floor were analyzed and processed using design of experiments. Both amplitude of vertical vibration and load to the floor were reduced with asymmetrical vibration isolation structure with larger left-side coefficient of dumper than the right side, and with larger right-side spring constant than the left side. This asymmetry was appeared because the drum rotates around counterclockwise while spinning. As a result, at the highest spinning speed, load to the floor was reduced 10% with asymmetric vibration isolation structure compared with the symmetric feature.
