摘　　要：研究并实现了一种基于工控机(IPC)和西门子高性能运动控制器Simotion的控制系统方案。针对伺服压力机传动系统采用伺服电机-蜗轮蜗杆换向减速机-传动螺杆-多连杆增力机构的结构形式,采用MSC.ADAMS软件研究螺母侧与滑块侧位移、速度关系,把用户设定的滑块速度-位移曲线转换成螺母的速度-位移曲线。基于模块化的设计思想,上位机软件采用C#语言开发,下位机软件采用IEC61131-3的结构化文本(ST)语言开发,上下位机之间基于UDP协议通讯。本系统已成功应用于自主研发的2000 k N机械多连杆伺服压力机,配合数控活动炉底加热炉、ABB机器人组成热成形技术生产线,已实际运行一年多,系统稳定可靠,扩展了传统压力机的工艺适用范围,提高了产品质量。A control system based on industrial personal computer （IPC） and Siemens high performance motion controller Simotion was researched and implemented. According to main transmission system of servo press, it was applied that the structure type of servo motorworm and worm gear commutation reducer-transmission screw-multi-link force increasing mechanism. The displacement and velocity relationships between nut and slider were researched by MSC. ADAMS software, and velocity-displacement curve inputted by user was transformed into that of nut. Based on the thought of modular design, upper computer software was developed by C# language, and lower computer software was developed by IEC61131 -3 structured text （ST） language. Upper computer and lower computer were communicated with each other by UDP protocol. The system has been successfully applied to a self-developed 2000 kN mechanical multi-link servo press in a production line of hot forming technology with CNC heating furnace and ABB robot for more than one year. The result shows that the system is stable and reliable, and it extends the technical application scope of traditional press, and improves product quality.
