A spur gear pair dynamic model for the gear dynamic contact loading, dynamic contact stress state and dynamic contact strain state analysis is presented. A dynamic model of the gear set with two degrees of freedom is used. The transmission is analyzed using the nonlinear finite elements method where a novel approach for interpreting the results of the stress and strain state using stress and/or strain tensor invariants is developed. For a more general approach, the software for the finite element analysis of the gear set as a whole is developed, using the open source finite elements framework CODE-ASTER/SALOME.

Key words: stress and strain state, dynamic load, stress and strain state analysis, spur gears, deformation, stress and strain tensor, finite element method.
