四杆打纬机构的运行监测和故障诊断

Vibration Monitoring and Fault Diagnosis of 4-Link Beat-Up Mechanism

本文探讨了无梭织机打纬机构的振动监测和故障诊断方法,利用筘座摆动系统的振动信号作时域和频域分析。在文章中,分析了机构运行状态与谱特性之间的关系,提出了信号诊断的各种判据以确定打纬机构的振动源。

This paper presents a method of vibration monitoring and fault diagnosis of 4-link me-chanism,by means of time domain and frequency spectral analysis.The relationship areanalysed between mechanism deterioration and failure and spectrum characteristic,and theimpact sources of mechanism are determined.
