For simple, efficient, and accurate conduct involute cylindrical gear transmission design, modeling, finite element analysis and optimization, in order to better fulfill its optimization design. With a pair of cylindrical gear for the study, using ChinaMachine software for the design of the drive gear, got their geometric parameters and the tooth root bending fatigue strength resuhs; then the big gear of the pair gears for the study, using CAXA for 2D modeling, combined with Pro/E for 3D modeling, combined with Solidworks for finite element analysis, got their two-dimensional and three-dimensional model and the results of finite element analysis for stress about the big gear and compared with the calculated values of ChinaMachine, and gives an optimized design flow gear. It has systematically studied that integrated using ChinaMachine, CAXA, Pro/E and Solidworks software for involute cylindrical gear＇s transmission design, modeling, finite element analysis and optimization is feasible.
