Optimization of the Hydraulic Synchronous Control Parameters Based on Simplex Method

300 MN die forging hydraulic press is the biggest die forging hydraulic press in our country, even in Asian, has made the tremendous contribution to our country´s national economy and the national defense development. The hydraulic synchronous control system is the important constituent of the hydraulic press, its blind area value, the return coefficient and the compensative flow relate the precision and the stability of the synchronous control system directly. This article, in the foundation of analysis of the moving beam´s stress model, uses the simplex method which the rate of convergence is quickly, carries on the optimization to above three parameters. The simulation result indicated that, under the maintenance of the system stable, chooses above parameters reasonably, can improve the moving precision and the response speed of the synchronous control system substantially.
