摘　　要：为有效确定伺服热模锻压力机中伺服电机的各项参数选型,以3台伺服电机通过行星减速器驱动的16 MN伺服热模锻压力机为研究对象,对伺服热模锻压力机的传动系统进行分析,将传动系统分解为曲柄滑块机构和行星减速器机构,并通过Matlab/Simulink建立数学模型。仿真结果表明:单台伺服电机在最大公称压力下所需的最大扭矩为18.83 kN·m,额定扭矩为6.278 kN·m,峰值功率为295.8 kW。同时,以伺服热模锻压力机曲柄滑块的上死点为起点,运行节拍为45次·min^(-1)时,曲柄滑块机构的最大等效转动惯量为502.232 kg·m^(2),行星减速器的最大等效转动惯量为40.98 kg·m^(2),单台伺服电机输出轴所需的最大负载等效转动惯量为15.335 kg·m^(2)。In order to effectively determine the parameter selection of servo motor in servo hot die forging press,for a 16 MN servo hot die forging press driven by three servo motors through a planetary reducer,the transmission system of the servo hot die forging press was analyzed,which was decomposed into a crank slider mechanism and a planetary reducer mechanism,and the mathematical model was established by Matlab/Simulink.The simulation results show that the maximum torque required by a single servo motor under the maximum nominal pressure is 18.83 kN·m,the rated torque is 6.278 kN·m,and the maximum power is 295.8 kW.At the same time,taking the upper dead point on the slider of the servo hot die forging press as the starting point,when the operating cycle is 45 times per minute,the maximum equivalent moment of inertia for the crank slider mechanism is 502.232 kg·m^(2),the maximum equivalent moment of inertia for the planetary reducer is 40.98 kg·m^(2),and the maximum load equivalent moment of inertia required by the output shaft of a single servo motor is 15.335 kg·m^(2).
