Transport package of a typical pulsation washing machine was taken as research object. Stacking, random vibration and drop tests were carried out and analyzed. It was primarily concluded that the key protection part was the clutch subassembly in the bottom of washing tub. An analysis model of the pulsation washing machine with cushion packaging was established; the model was then simplified; and mechanical calculation was carried out. It was proved theoretically that the primary conclusion is correct. The protection measures of the key protection part of pulsation washing machine were analyzed. The purpose was to provide reference for packaging structure design for key protection part of pulsation washing machine.
