Predicting Unmeasured Region of the Efficiency Map of a Speed Reducer Using a Denoising Auto-Encoder

摘要

This paper presents a Remaining Useful Life (RUL) prediction method for a speed reducer based on denoising au- to-encoder (DAE). Constructing the efficiency map of the reducer is an important process for predicting the life span. However, due to the situational constraints that occur, un-measured intervals hinder the completion of the efficiency map. to solve this problem, we propose a method that can predict and reconstruct an unmeasured interval effectively and reliably by using DAE. In addition, we examine the applicability of the proposed algorithm through experiments that assume various situations.
