摘要
本文讨论了分析机械诊断信号的一种新方法——Wigner分布及其在机械监测及诊断中的初步应用。简单介绍了Wigner分布的物理意义及主要性质。通过模拟分析及实验研究探讨了用Wigner分布处理诊断信号的优点。
A new method of analyzing machinery diagnostic signals ——Wigner distribution and its preliminery applications in machinery monitoring and diagnosis are discussed in this papper. The physical interpretations and important properties of Wigner distribution are introduced briefly. The advantages of Wigner distribution in diagnostic signal processing are discussed through analytical and experimental research.
