为了提高巨型模锻液压机同步控制系统的快速响应性，在300 MN 模锻液压机的基础上，针对800 MN 模锻液压机的特点重新设计了同步控制系统，并基于液压基础理论和动力学理论，联合建立了活动横梁运行时同步控制系统的整体数学模型。将原方案和现有方案进行了对比仿真，结果表明：新设计的800 MN 同步控制系统的响应特性较原方案的响应特性有较大幅度的改善，响应速度和动静态精度均有较大提高。

In order to improve the rapid response of a giant die forging hydraulic press synchronous control system,based on 300 MN die forging hydraulic press,the synchronous control system was re-designed according to the characteristics of 800 MN die forging hydraulic press,and based on hydraulic theory and dynamics theory,a model of the synchronization control system was jointly established when moving beam run.On the basis of that,two kind of schemes were compared through simula-tions,the simulation results show that the new design of 800 MN synchronous control system response characteristics is substantially improved,the response speed and dynamic and static precision are of a large improvement.
