Application of SAX in temperature monitoring of friction welding

( Volume 6 Issue 3,March 2019 ) OPEN ACCESS

Du Kun


In this work,we introduce the new way to find problem in frictionwelding.SAX is a new way to find discords. Symbolic aggregate approimation(SAX representation) is a time series dimensionality reduction technique which benefits from its brief represention in dimensionality reduction and high-performance lower bound distance algorithm. In friction welding process, temperature is an important index to judge whether the machining is normal or not.SAX method provides a fast and efficient way for temperature detection, which can quickly find the abnormal region of temperature data.This method can quickly detect the location of the abnormal area and find the cause of the exception.
