基于声发射的磨削信号曲线处理

The Disposition on Grinding AE Signal Curve

本文利用声发射传感器对磨削加工过程进行在线实时信号采集,同时使用振动传感器对系统振动进行测量,通过DATAQ仪器进行初步消振处理,并实现声发射信号在PC机上实时采集、保存。对所获得单个加工件加工过程声发射曲线,采用消记忆递推算法进行处理,使曲线光滑规则,为进一步分析处理磨削信号,优化监控磨削过程,提供更有效的工具。

The main contents of this paper are the collection of Acoustic Emission （AE） of gtinding and the process of the AE signal. The AE signal data are collected real-time through AE sensor for on-line monitoring of grinding processes based on experiments. A vibrating sensor and DATAQ instruments are used to weaken vibration preliminary and to make the collection and the preserving of the RMS of AE on PC. The procession and analysis of process curve of each single workpiece in a production line of automotive components based on the eliminatiou-anamnesis recursion method （EARM）, which can eliminate the interference and vibration, providing a more effective method for analyzing and processing grinding.
