摘 要: The vibration signal generated from a faulty roller bearing can be analysed by a variety of techniques. In order to ascertain the optimum method to apply to bearings associated with conveyor belts used by a pharmaceutical company, it was decided to study four different common faults in bearings on a suitably constructed rig. The seeded faults were damage to the rolling element, faults in the outer race and faults in the inner race respectively. Investigations were then carried out with Spectrum analysis, Cepstrum analysis, Envelope Signal Processing, Bispectrum Analysis and the Spectral Kurtosis Method. The advantages and disadvantages of each technique for the faults in question are discussed.

由故障滚子轴承产生的振动信号可通过多种技术进行分析。为了确定适用于制药企业输送带轴承的最佳方法,决定在适当搭建的试验台上研究四种常见的轴承故障:分别为滚动元件损伤、外圈故障和内圈故障。随后采用频谱分析、塞普斯特姆分析、包络信号处理、双频谱分析以及谱曲率法对这些故障进行了研究,并讨论了每种技术在分析上述故障时的优缺点。
