摘要
谐波小波具有在频域良好的盒形谱特性、存在明确的函数表达式、时频定位准确和算法实现简单等优点。本文结合实例应用谐波小波提取动平衡机不平衡量信号,有效地滤掉了信号中混杂的低频和高频干扰。
Harmonic wavelet has advantages such as box-like spectrum in frequency domain, existing certain function expression, locating precisely in time-fequency domain and simple algorithm. In this paper, harmonic wavelet is applied to extract unbalance signal in dynamic balancing machine and filter effectively out high-frequency and low-frequency interferences from the desired signal.
