This thesis applies fuzzy theory to fuzzy optimum design and evaluation of common cylinder worm drive, which takes worm module, worm characteristic coefficient and number of heads of worm as variables and minimum corona mass as target function.

• 以普通圆柱蜗杆传动的蜗杆头数、轮模数、杆特性系数为设计变量,以蜗轮齿冠质量最小为目标函数,应用模糊理论对普通圆柱蜗杆传动进行模糊优化设计与实例验算。
