摘　　要：分析精校机液压伺服系统的工作过程,建立精校机液压伺服系统的数学模型,绘制系统开环和闭环Bode图,并对其动态特性和稳态响应精度进行分析。分析结果表明:该系统的频宽较大,响应快速性较好。该方法为精校机产品的设计和制造提供参考。The work process of hydraulic servo system of precise straightening press was analyzed, and the mathematic model was built. The bode graphs of open system and close system were drawn. The dynamic character and static responding precision were analyzed. The results show the system frequence width is wider, and responding rapidity is better. The method provides reference for designing and manufacturing precise straightening press.
