A FEM software specializing in analysis of gear pair has been developed. In the software, a new non-conventional element ; tooth flank film element, is applied to give easily boundary conditions between contacting tooth flanks. The purpose of the present study is to confirm the usefulness of the developed software ; i.e., validity of the tooth flank film element. For this purpose, the calculated distribution of contact stress between tooth flanks was compared with the measured one. A pressure measurement film is used for measuring the contact stress. However, the film alters the boundary condition near the contact point, because its Young's modulus is much smaller than that of steel. In the FEA, therefore, Young's modulus of the tooth flank film element was set to be identical to that of the pressure measurement film. As a result, the calculated and measured stress showed good agreement.
