摘　　要：介绍了齿轮箱故障振动信号传统的时域、频域分析方法,并列举了一些不同故障所应用的分析方法。齿轮箱由于变工况运行时转速不稳定、负荷变化等状况而产生非平稳信号,因此介绍了一些基于非平稳信号处理的方法特点及应用,并指出了齿轮箱故障诊断的发展趋势。The traditional time and frequency domain methods of vibration signals of gear box fault are introduced in this paper. And meanwhile this paper lists different applied fault analysis means. Because of changing work condition, gear box will produce non-stationary signal in the case of the non-stationary rotated speed and non-stationary load. This paper introduces the characteristics and application of the processing methods of the non-stationary signal and points out the developing trend of fault diagnosis of gear box.
