摘　　要：控制套印误差是现代印刷技术的重要课题,而印刷机滚筒在旋转过程中表面各点的切向位移偏差是套印误差产生的主要原因。为此,论文设计并实现了旋转部件切向位移偏差实时监测系统,该系统利用光电检测以及模/数混合信号处理方法实现了对印刷机套印误差的实时监测,可用于高精度印刷机械的研发与制造过程。系统采用了条形码编码技术、虚拟标尺技术、动态切向位移偏差实时测量技术以及自适应动平衡技术4项关键技术,测量精度可达到±10μm。Controlling overprint error is an important for modern printing technology,and the displacement deviation of press cylinder surface in high-speed rotation state is a major cause of overprint error.The real-time monitoring system for detecting the tangential displacement deviation in rotating parts was designed and implemented.Photoelectric detection and A/D mixed-signal processing method was used to realize real-time monitoring of the press overprint error,which could be used for research and manufacturing process of high precision printing machinery.Barcode coding technology,virtual calibration technology and real-time monitoring technology for tangential displacement deviation and self-adaptive dynamic balance technology were used in the system,and the measuring precision was controlled within ±10μm.
