Dehydration dynamics model with Monte Carlo Method for a front-loading washer/dryer

Abstract

In this study, we aimed to improve the efficiency of an anti-vibration design for front-loading washer/dryers and propose a dehydration dynamics model that combines a mechanical model with a random algorithm. In addition to the anti-vibration structure, front-loading washer-dryers are equipped with dehydration start control where dehydration is repeated until the level of vibration detected during dehydration falls below the threshold. The proposed model focuses on the probability distribution of clothing behavior during dehydration and models the clothing behavior by using a random number that follows the probability distribution. Then, we present the reusability of the probability distribution and the difference from a mechanical model that does not consider clothing. In this way, in the upstream design without the actual machine, the anti-vibration structure and dehydration start control could be simultaneously designed, improving the efficiency of the anti-vibration design.
