瑞典Fundia钢公司为了消除轧机传动件(如联轴节和齿轮箱)机械共振现象,安装了驱动软件控制器进行现场试验并己取得成功。该软件控制器被称为共振频率消除器(简称RFE),用它可提高生产率,降低成本。当轧机受到钢坯冲击出现减速时 Fundia Steel, Sweden In order to eliminate mechanical resonance phenomena in rolling mill transmissions such as couplings and gearboxes, a drive software controller was installed and tested on site and has been successful. The software controller is known as the Resonance Frequency Eliminator (RFE), which increases productivity and reduces costs. When the rolling mill suffered billet impact deceleration
