摘要：

高性能复杂整体模锻件要求巨型模锻液压机必须具备多缸同步运行的能力，但由于锻件材质不均、形状不对称等原因，巨型模锻压机极易出现活动横梁倾斜现象。针对这一问题，本文建立了模锻液压机同步系统的数学模型，在考虑模锻压机各工况特点的基础上，对同步系统性能进行了仿真验证。通过对仿真系统的综合分析得了压机系统各参数对同步性能的影响规律，以及提高压机同步系统稳定性、控制精度、抑制最大偏转角以及缩短纠偏时间的方法。

High-performance complex whole forgings require the giant forging press having the ability of multi-cylinder synchronous operation. However, because of the uneven material, asymmetrical shape and other factors, the giant forging presss movable beam is easily prone to tilt. Considering this problem, a mathematical model of synchronization system was firstly established. And then, on the basis of considering various working conditions, performances of synchronization system were verified by simulation. At last, by a comprehensive analysis of the simulation system, the influence law of parameters of synchronization system on its performance was obtained, and the ways to improve stability of system and controlling precision, suppress the maximum deflection angle and shorten the correction time were got.
