采用正交设计与数值模拟相结合的办法,对航空发动机用GH4169合金盘件的ACDR过程进行了有限元分析,提出采用“望目”型目标函数对盘件热力参数进行评价。结果表明:工件所需的成形载荷主要取决于上模的倾角,应变分布情况主要取决于上模的每转进给量,而温度分布受各工艺参数的共同影响。在此基础上,获得了最佳的工艺参数组合。 The ACDR process of GH4169 alloy plate for aeroengine was analyzed by means of orthogonal design and numerical simulation. The objective function of GH4169 alloy plate was proposed to evaluate the thermal parameter of plate. The results show that the forming load required for the workpiece mainly depends on the inclination of the upper die. The strain distribution mainly depends on the feed per revolution of the upper die and the temperature distribution is affected by the process parameters. On this basis, the best combination of process parameters was obtained.
