A new method for calculating the mesh stiffness of gear transmission system which was the foundation of gear dynamics analysis was proposed based on finite element method.To validate the calculation method,a spur gear pair was adopted to calculate the mesh stiffness.The results show that the mesh stiffness is identical with that from ISO 6336 method.Subsequently,the proposed method was used to calculate the mesh stiffness of face gear transmission system,and the change law of the meshing stiffness for the face gear transmission system was researched.The research results provide the basic condition for dynamics analysis and design of face gear transmission.
