摘要：

为了实现连杆热锻过程的绿色设计，针对TC4钛合金连杆的热锻过程的单位体积能耗，采用有限元软件Deform3D构建连杆的有限元模型，运用正交实验方案探究了锻坯初始温度、锻造速度、压扁量、摩擦因数4个工艺参数对单位体积能耗的影响。通过极差分析得到了各因素对单位体积能耗的影响程度：摩擦因数对单位体积能耗的影响程度最大，其次为锻坯初始温度和锻造速度，压扁量对单位体积能耗的影响最小；确定了优选方案工艺参数组合为：锻坯初始温度为1010 ℃、锻造速度为550 mm·s-1、摩擦因数为0.1、压扁量为10 mm。在优选后的工艺参数条件下进行了连杆样品锻造，单位体积能耗由原来的418.54 J·mm-3下降至288.17 J·mm-3，降幅达31.15%。TC4钛合金连杆热锻样品的金属填充正常，无锻造缺陷，实现了绿色制造。

In order to realize the green design of hot forging process for connecting rod, for the energy consumption per unit volume of the hot forging process for TC4 titanium alloy connecting rod, the finite element model of connecting rod was constructed by the finite element software Deform-3D, and the influences of four process parameters such as initial temperature of forging billet, forging speed, flattening amount and friction factor on the energy consumption per unit volume were investigated by the orthogonal test. Then, the influence degree of each factor on the energy consumption per unit volume was obtained by the range analysis. And the friction factor has the greatest influence on the energy consumption per unit volume, followed by the initial temperature of forging billet and forging speed, and the flattening amount has the least influence on the energy consumption per unit volume. Furthermore, the optimal combination of process parameters is determined as the initial temperature of forging billet of 1010 ℃, the forging speed of 550 mm·s-1, the friction factor of 0.1, and the flattening amount of 10 mm. Finally, the forging of connecting rod sample was carried out under the optimized process parameters. The results show that the energy consumption per unit volume decreases from 418.54 J·mm-3 to 288.17 J·mm-3, which has a decrease of 31.15%, and the metal filling of the hot forging sample for TC4 titanium alloy connecting rod is normal, without forging defects, which realizes green manufacturing.
