Abstract

In this study, vibration analysis of washing machine dehydration was carried out using laser sensors. The suspension of the washing machine was attached to a jig developed for this study. In addition, 10 laser sensors were attached to the jig. The channels of each laser sensor are composed of five channels: front, rear, left, right, and upper. Data acquisition equipment was used to obtain sensor data. The measured data were processed using signal processing, and interpolation of the data was performed using MATLAB with robust interpolation. Vibration analysis according to unbalanced mass and sensor attachment points was carried out.
