Based on gear geometry and experimental research,the prophase fault diagnosis analysis of power-train axle shell about vehicle was studied.Theory analysis and test data indicated that the experimental method was feasible.At the same time,using the least square method to predict the indexes,it also could be concluded that a two order mul-tinomial was applied to predict RMS,while a three order multinomial was applied to predict kurtosis.
