摘　　要：将灰色关联分析方法和模糊逻辑推理技术应用于圆柱直齿轮锻模的正交优化设计,以分流角、凸模成形角、反向凸模成形角和分流距4个齿轮锻模设计的关键参数作为设计变量,以成形时所需工作载荷最小和成形后齿轮件端面机械加工余量最小为优化目标,找到了一组最佳的设计参数组合,与单一追求工作载荷最小或加工余量最小的参数组合相比,该组参数使综合评价指标提高了0.0879。Grey relational analysis method and fuzzy logic reasoning technique were used to orthogonal optimial design for the gear forging dies with four key parameters. Both of the service load and allowance for finishing gear forging process were used as evaluating indicator in the optimization, and the aggregative indicator was the fuzzy reasoning grades of the grey relational coefficients of each evaluating indicator. Finally,the optimal group of design parameters which can minimize both service load and allowance for finish was found. Compared with the parameter groups of minimum service load or allowance for finish, the aggregative evaluating indicator is improved by 0. 0879.
