摘要：
The dynamic response of contact mechanics has significance important for durability and reliability design of gears. A finite element analysis model for dynamic response of contact mechanics of gear pair is established, and then the contact fatigue life of gear pair is analyzed based on the finite element model. The key parameters of contact finite element model is determined through the contact finite element analysis of thin cylinder. The precise finite element analysis model of the gear meshing is established and calculated by transient dynamics. The contact force and contact stress of different position is obtained. Through change friction coefficient of finite element model, the influence of friction coefficient for contact force and contact stress is obtained. Comparing the life of traditional risk point calculated in most of the standard and dangerous point which has the max stress through simulation. The influence of friction coefficient on contact life is determined.
