摘要
针对气动板形检测辊内表面存在机械加工误差而产生系统圆周误差,从而导致静态标定曲线偏差的问题,设计了一套动态标定装置,采用光纤传感器对检测辊进行鉴相定位,实现对系统圆周误差的补偿,并采用虚拟仪器LabVIEW技术开发了气动板形检测辊动态标定软件系统。实验表明,该方法有效消除了系统圆周误差,由动态标定方法所得出的检测辊特性曲线更加准确,且实验过程更加接近实际的板带轧制过程。
Circumferential error is imported to the pneumatic strip shape measuring rolls for machining error in rolls'inner interface, and leads to static calibration curve error. To get the real character curves of pneumatic strip shape rolls,a dynamic calibration method is proposed and experiment device is designed. An optical fiber sensor is used to correct phase,which provide signals to compensate circumferential error,and dynamic calibration system for pneumatic strip shape roll based on LabVIEW is developed. Experiments prove the effectiveness of proposed method. The character curves of measuring rolls from dynamic calibration method are more precise,and the experiment way is closed to the real process,the results can be applied to real shape control system.
