【摘要】 在电主轴故障机理分析的基础上,得出反应电主轴故障信号的监测参数,将监测数值与安全阈值相比较,可实现故障预警与监测。利用小波包对故障信号的分解与重构、倒频谱分析等,实现电主轴故障离线诊断,能有效确定电主轴故障的详细信息。更多还原

【Abstract】 Based on analyzing failure mechanism of tools spindle,the monitoring parameters,responding to spindle failures,have been found.It will have come true that monitoring failures and early warning,by comparing monitoring data with safety threshold.Decomposing and re-organizing failures signals by using wave packet,and cepstrum analysis,it can make a off-line diagnosis aimed to spindle.It can effectively identify detailed information of spindle failures.更多还原
