Aiming at the signal processing problems that exist in online fault diagnosis for train running gear, based on discussing the principle of characteristic spectrum analysis, a method of full period and uniform angle sampling is applied, which transfers the vibration signal from time domain into angular domain. The angular domain signal is transferred into corresponding characteristic spectrum using FFT. Through spectrum estimation and analysis, fault characteristic spectrum values of running gear components are acquired to distinguish their faults.

Analyzing the honing principle of spiral bevel gears based on crossing-axis transmission, the mathematical model of the relative sliding speed of the contact point between honing wheel and gear is achieved. It is determined that the pitch cone of honing wheel depends on the number of teeth in the honing wheel and the angle between the common normal of pitch cones and the plane parallel to both gear and honing wheel axes.
