基于振动信号分析的数控机床自动换刀系统故障诊断研究
Research on Fault Diagnosis of CNC Machine Automatic Tool Change System Based on Vibration Signal Analysis
摘要
Abstract
Taking the automatic tool changing system of the disc-type tool magazine manipulator in the machining center as the research object,adopts the Laplace wavelet to construct the parameter pulse dictionary,uses the split augmented Lagrangian shrinkage algorithm to solve the sparse representation coefficient,and extracts the vibration during the automatic tool changing cycle.The transient characteristics of the signal are characterized by parameters such as frequency,damping ratio,occurrence time,etc.,which realizes the accurate extraction of system fault characteristics,improves the accuracy of state analysis and diagnosis of the automatic tool changing system,prolongs the normal working time of the automatic tool changehe system,and enhances the reliability of the system.关键词
