摘　　要：针对高肋、薄壁钛合金叶栅环的结构特点,借助三维有限元模拟方法,分析了等温成形中始锻温度、下压速度和摩擦因子对叶栅环成形质量的影响规律。选取优化后的工艺参数进行物理实验研究,结果表明,始锻温度为920℃,下压速度为0.5 mm/s,摩擦系数为0.1时的工艺条件下,可以得到满足质量要求的等温锻件。Based on the structure feature of high-rubbed and thin-walled titanium alloy blade,the effects of the initial forging temperature,velocity and friction factor were studied with the method of FEM simulation, Selecting the optimized process parameters for physical experiment, the results show that under the conditions of initial forging temperature of 920℃ ,press speed of 0.5mm/s, friction coefficient of 0. 1 ,the isothermal forging products can meet the quality requirements.
