摘　　要：提出了一种基于有限元数值模拟和响应面法对叶片精锻工艺的优化方法,给出了表征叶片锻模型腔填充特性的新型目标函数,讨论了叶片平衡角及毛坯尺寸对叶片锻模填充过程的影响,构造了目标函数对设计变量的响应面函数。以钛合金叶片精锻过程为例,应用所提出的方法对现行工艺条件下的叶片平衡角和毛坯宽厚比进行了组合优化,所得结果有助于钛合金叶片精锻工艺设计和钛合金叶片锻件质量控制。Using FEM and RSM, a new optimal method for blade precise forging process was introduced, a new objective function was established to characterize the dies cavity filling of blade forging and to get the response of the objective function to the design variables. Taking a blade forging of titanium alloy as example, the primary process parameters under current technological conditions were optimized. The results benefit the blade precise forging process desgin and quality control of titanium alloy.
