1)model in the grey system theory is proposed to predict the test data of fatigue life of gear
the aim is to large1y cut short test time
save test cost
quickly obtain the reliability index.The principle of the grey GM(1
1) model is introduced
through specific example
the GM(1
1) model of gear fatigue life is establish.The calculation result shows that a higher accuracy could be obtained by applying the grey system theory to predict the test data of fatigue life of gear
and a valuable method is proposed for shortening the test time of fatigue life of gear.
