Research On Test Method Of The Paper Transverse Vibration In Web Press

With the high speed movement of the web press,it’s inevitable to produce the vibration problem of the paper,in which the vibration perpendicular to the vertical direction of the tape is called transversal vibration.At present,the domestic and foreign scholars have studied of the transverse vibration,such as mechanical analysis,theoretical modeling and vibration control,didn’t measure the lateral vibration of the paper.The main research of this topic is to design a kind of web press transverse vibration test system,perform the actual measurement of the paper transverse vibration.The main task and innovation topics are as follows:(1)Study on the characteristics of the paper transverse vibration in web press.Analysis of the conventional vibration testing method of a thin film,the paper transverse vibration is transformed into the distance measurement.In the end,use ultrasonic ranging system as the method.(2)In order to improve the accuracy of the measurement results,design of the dual probe measurement scheme.After analyzing the measured data,the direction of the paper transverse vibration is calibrated.(3)Select the appropriate ultrasonic probe and set the distance.The system use of the MSP430F149 ADC12 module,to convert the analog quantity obtained by the ultrasonic distance measurement into the data quantity;Complete the test system hardware circuit,the machine program and the computer software development.(4)After commissioning the test system,using paper jitter to simulate the paper transverse vibration in web press,in time the paper transversal vibration data displayed,and stored in a graph.The test system was verified to achieve the expected target,and finally verified the test system to achieve the objectives of the project.
