摘要
介绍了不平衡振动的机理;分析了HSK刀柄产生不平衡的原因和振动信号的特征;阐述了信号预处理的方法;最后利用小波理论进行小波变换重构信号,更准确的提取了HSK刀柄的振动信号,为今后的科学研究和HSK综合测量系统的开发提供了很好的依据。
The principle of unbalance vibration is introduced in it.Then the reasons causing unbalance of HSK shank and the features of vibration signal are analyzed.Afterwards the method of signal preprocessing is described.Finally,by transforming and reconstructing the vibration signal with wavelet theory,more accurate vibration signals of the HSK shank are extracted,which provides better basis for scientific research and the development of the HSK integrated measurement system.
