Based on tooth surface simulation of spur face gear

the automation from parametric modeling to load tooth contact analysis of face gear pair in finite element software is achieved by using Matlab and ANSYS.To solve the problem of stress calculation while design face gear

the exact relationship between load and bending stress of face gear is researched

and a method to predict the bending stress by artificial neural network is presented which regard the result of finite element analysis as samples

the method can rapidly calculate the bending stress with high accuracy while parameters are within sample scope.The foundation for strength design of face gear is laid.
