摘要：

为提高同步器齿环热精锻成形的材料利用率，提出一种基于响应面模型（Response Surface Method, RSM）与粒子群算法（Particle Swarm Optimization, PSO）结合的工艺参数优化方法。分别选择坯料始锻温度、压制速度、摩擦因子和坯料高度作为设计变量，并借助数据归一化法和线性加权法等数据处理方法，建立齿环热精锻成形综合加权评分值与主要工艺参数的响应面模型，在可行域范围内，采用粒子群算法，寻找响应面模型的最优解。结果为：坯料始锻温度T=725 ℃，压制速度v=200 mm·s-1，摩擦因子μ=0.4，坯料高度h=15.5 mm。最后，通过CAE分析和生产试制进行验证可知，齿环锻件充填饱满，未见折叠缺陷，材料利用率提高了9.44%。

In order to improve the material utilization in hot precision forging for synchronizer ring, an integrated optimization strategy was proposed based on response surface model (RSM) and particle swarm optimization (PSO), and the response surface model with the weighted grading values and the main process parameters was established by selecting the initial billet temperature, punch velocity, friction factor and billet height as design variables based on the data normalization method and the linear weighted method. Then, the best result of the predictive model in the feasible solution space was searched. The results show that the optimal process parameters are the initial billet temperature of 725 ℃, punch velocity of 200 mm·s-1, friction factor of 0.4 and billet height of 15.5 mm. Finally, the production practice and CAE analysis show that the synchronizer ring fills full without fold, and the material utilization increases by 9.44%.
