切割设备在大进给,大切深的作业工况下易出现切割片断裂飞崩的情况,会降低切割效率并且造成人员危险。通过提取作业时的振动加速度信号从时域和频域两个方面进行分析,利用小波包变换的方法对振动信号进行逐层分解,得到了不同进给速度下...展开更多 切割设备在大进给,大切深的作业工况下易出现切割片断裂飞崩的情况,会降低切割效率并且造成人员危险。通过提取作业时的振动加速度信号从时域和频域两个方面进行分析,利用小波包变换的方法对振动信号进行逐层分解,得到了不同进给速度下升降工装切割作业的振动特性。建立切割片横向振动方程研究振动的产生机理并分析切割故障时信号特征的产生原因及影...

Under the working conditions of large feed and deep cut,the cutting piece is prone to break and crash,which will re-duce the cutting efficiency and cause danger to personnel.By extracting the vibration acceleration signal from the time domain and frequency domain,the vi...MORE Under the working conditions of large feed and deep cut,the cutting piece is prone to break and crash,which will re-duce the cutting efficiency and cause danger to personnel.By extracting the vibration acceleration signal from the time domain and frequency domain,the vibration signal was decomposed layer by layer by usin...
