基于遗传算法的双圆弧齿轮传动的模糊可靠性优化设计

Optimization design of fuzzy reliability of Novikov gears driving with double circular arc tooth profiles on account of genetic algorithm

以圆弧齿轮传动的小齿轮齿数、法面模数、螺旋角及齿宽的均值为设计变量 ,以两圆弧齿轮的体积之和最小为目标函数 ,应用模糊设计理论和可靠性设计理论 ,建立了双圆弧齿轮传动的模糊可靠性优化设计的数学模型 ,采用遗传算法对其进行优化 ,结果表明 。

The smaller gear's number of teeth and normal module and helix angle and averaging of tooth width are regardes as variable in circular gear's driving design,the smallest volume sum of the two circular gear is realized as the objective function in this paper,the designing theory of fuzzy and reliability are applied and the fuzzy reliability optimization design's mathematical model of Novikov gears driving with double circular arc tooth profiles is built,by using method of genetic algorithm is optimized, the result addressed the effect is right.
