摘要:

 根据汽车转向节热锻成形过程中的主要影响因素即坯料始锻温度、模具预热温度、上模运动速度和摩擦因数,运用DEFORM 3D软件对汽车转向节热锻成形过程进行了数值模拟,并应用正交实验法对数值模拟结果进行分析。结果表明:随着始锻温度的升高,转向节在热锻过程中的最大等效应力减小,能量和金属最大流动速度增大;随着上模预热温度增加,转向节热锻过程中的最大等效应力逐渐减小,能量和金属最大流动速度逐渐增大;随着上模运动速度增加,热锻转向节的最大等效应力先减小后增加,能量和金属最大流动速度呈现增大趋势;随着摩擦因数增大,转向节的最大等效应力和金属最大流动速度呈先减小后增大的趋势,能量逐渐增大,并通过比较极差值R判断了各个因素的主次关系。

  Based on the main influencing factors of initial forging temperature for billet, die preheating temperature, upper die movement speed and friction coefficient during the hot forging process of automotive steering knuckle, the hot forging process of automotive steering knuckle was simulated by using software DEFORM 3D, and the numerical simulation results were analyzed by the orthogonal experimental method. The results indicate that with the increasing of initial forging temperature, the maximum equivalent stress during the hot forging process decreases, and the energy increases and maximum metal flow velocity increase for the steering knuckle. With the increasing of die preheating temperature, the maximum equivalent stress during the hot forging process of automotive steering knuckle gradually decreases, while the energy and maximum metal flow velocity gradually increase. With the increasing of upper die movement speed, the maximum equivalent stress initially decreases and then increases, while the energy and maximum metal flow velocity show an increasing trend. In addition, with the increasing of friction coefficient, the maximum equivalent stress and maximum metal flow velocity of steering knuckle first decrease and then increase, and the energy gradually increases. Thus, the primary and secondary relation of each factor is determined by comparing range values R.
