摘　　要：目的为了解决卷筒纸印刷机高速运转时带来的纸带横向振动问题,设计一种高精度卷筒纸印刷机振动测试系统。方法把纸带的横向振动转化为距离测量,采用超声波测距的方法对纸带横向振动量进行测量,利用MSP430单片机自带的AD进行模数转换,把超声波探头输出距离的模拟量转化成数据量输出,显示在液晶屏上,并在PC端设计上位机软件,通过串口通信把测量的数据进行实时显示。结果通过对测试系统的实验,得到了实时的振动数据,经测试,该系统对振动纸张进行检测的精度达到了0.1 mm。结论通过超声波测距方法设计出一套卷筒纸印刷机纸带横向振动测试系统,减小了测量误差,提高了测量精度。The work aims to design a high-precision web press vibration test system to solve the problem of lateral vibration of the tape when the web press runs at a high speed. The lateral vibration of the tape was converted to distance measurement, and measured in the method of ultrasonic distance measurement. The analog-digital conversion was conducted with AD attached to MSP430 single chip microcomputer, to convert the analog quantity of ultrasonic probe output distance into the data amount output, display it on the LCD screen, and design PC software at the PC terminal. The measured data were displayed in real time through the serial communication. Through the experiment of the test system, the real-time vibration data was obtained. After the testing, the detection accuracy of the system for the vibration paper reached 0.1 mm. Through the method of ultrasonic distance measurement, a set of transverse vibration test system of web press tape is designed, which reduces the measurement error and improves the measurement accuracy.
