Abstract：

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.
