Modeling of tilted type automatic washing machine under dehydration process

抄録

Recently, washing machines are demanded to reduce noise and vibration due to the changes of lifestyle such as the number of people who both work increased and other various reasons that the laundry can only be washed at night. To avoid serious troubles by noise in the neighborhood, especially the vibration in dehydration process in a washing machine has to be reduced. Vibration and noise of a washing machine are caused by unbalanced mass of clothes being washed on one side in the washing tub. To resolve this problem, it is important to research vibration characteristics of washing machine. Therefore, the purpose in this paper is to create the vibration analysis model of a tilted type washing machine considering the influence of fluid balancer. The mechanism of the balancer is that the working fluid in the balancer is automatically moved to a position against the unbalanced mass during drying process (high speed rotation) to cancel the unbalanced load. In this model, the fluid inside the fluid balancer is expressed as 36 balls with 6 baffle boards. These baffle boards are installed to prevent the fluid from being too biased to one side. This model is created by using ADAMS. First, verification is performed with an eccentric load of 300g. After that, the model is tested at an eccentric load of 500g to verify whether the model is effective under other conditions. As a result, it was found that this model is effective at certain eccentric loads and rotational speeds.
