摘　　要：介绍了函数逼近的有限元优化方法基本理论,利用ANSYS的可编程和参数化建模功能建立整个优化分析的流程,程序随着迭代自动生成有限元模型和边界条件。通过优化计算发现,其他参数相同而模数不同的双圆弧齿轮其齿根强度最优的齿形参数一致,且最优齿形是一种接近于公切型双圆弧齿轮的齿形。Basic theory for the finite element optimization method of functional approach was introduced. The flow diagram of the entire optimization analysis was established by the use of the functions of programmable and parametric modeling of ANSYS. Finite element model and boundary conditions were generated automatically by the program along with the itera- tion. By means of optimal computation it is discovered that the double circular arced gears with different modules but the same else parameters have the identical tooth shape parameters of optimal dedendum strength and their optimal tooth form is closing to the tooth form of the common tangent typed double circular arced gears.
