摘要
为了准确测量机械转子的不平衡量,开发了基于Lab VIEW的转子在线动平衡测量分析系统。该系统采用相关分析的方法对机械转子动态振动信号进行时频分析,实现对振动信号幅值和相位准确提取,并用影响系数法求解不平衡量。充分利用Lab VIEW丰富的库函数和强大的计算分析及信号处理功能,设计了一种可靠、便捷、准确的动平衡在线计算测量方法。
To accurately measure the unbalance mass of the mechanical rotor, an online dynamic balance testing and analytic system based on LabVIEW is developed in this paper. Correlation analysis method is used to analyze the dynamic vibration signal of the mechanical rotor by spatial and frequency domain to accurately attain the amplitude and phase of vibration signal and solve the unbalance mass with the influence coefficient method. The experimental results show that the proposed method is a reliable, convenient and accurate dynamic balance online calculation method.
