| In this paper, we use the experiment to research the 3D displacement sensor in the application of the drum washing machine. Firstly, the research object is a 3D displacement sensor, analyzing its working principle. Secondly, the Measurement System has been evaluated(Measure-ment System Evaluation, for short MSE), to ensure the precision of the Measurement System. Last but not the least, measure three axial vibration displacement in the process of the spin of suspension system. The unbalance location has been determined through the analysis of test data, and the experiment has been done in the different machines to ensure the reliability of test results. |
