The Basic Research to Classify the Completion of Gearbox from Operating Sound for Skill Evaluation in Technology Education

Abstract

It is important for the security operating of the machine to carry out the diagnosis of conditions. Many diagnosis methods based on the operating sound have been proposed because abnormal conditions are often suggested by abnormal sound of the working machine. This paper explains to classify method from operating sound of the gearbox. And, this classify method is utilized in skill evaluation for technology education. First, modeling error based on autoregressive models from a sound data are used as the classification of gearboxes. Next, this paper adopts this classification method as the achievement metrics for the assembling of gearboxes. Finally, the evaluation of this approach is verified in the experimental working by undergraduate students.
