For the contact fatigue failure problem of vehicles’ hypoid gears under complex conditions, the rain-flow counting method and Goodman’s average stress equation were used to establish a contact statics model.The load-time history of the contact gear surface was extracted. And the load spectrum of hypoid gears was produced.The research focused on predicting the high-cycling fatigue life of hypoid gears based on the load spectrum.The study also utilized the finite element method to simulate gear teeth’s meshing or contact behaviour under loading conditions. Moreover, the influence mechanism of fatigue damage criterion on the gear fatigue life prediction was revealed.The proposed method is highly significant in assessing and predicting the high-cycling fatigue life of vehicles’ hypoid gears.
