Corrugated Roller Vibration Analysis And Structure Optimization

Corrugated roller is the most important parts of stare blankly cardboard productionand a core part of the single stare blankly machine. Corrugated roller is a hollowcylinder shaft, made up of two shaft and a cylinder head, shaft head is covered withcylinder, attaches the tightness of weld link. Corrugated roller is divided into the uppercorrugated roll, corrugated roller and pressure roller, the upper corrugated roller providecontact pressure, the lower corrugated roller is the active part. The loader corrugatedroller forms in a crown in the course of the working process. If the amount is too small,the intermediate pressure is not enough, thus making corrugated’s shaping not sufficient,or wandering, discounts etc. If the amount of convex is too large, the middle pressurebecome too big, pressure on both ends gets too small and tear the corrugated base paper,or stare blankly phenomenon, it also accelerate the wear of the corrugated roller andreduce the lifetime of the corrugated roller.This topic from the dynamic simulation of corrugated roll, corrugated roller for thefinite element analysis, The action of stress and displacement changed, under corrugatedroller load rotate speed, temperature, pressure, gravity. Corrugated roller have beencalculated in motion when axial the largest displacement, degree of camber, stress,corrugated roller tooth contact stress and the stress distribution inside the cavity, Toprovide evidence for optimize the design of corrugated roller structure; At the same timeon the corrugated roller statics, dynamics analysis, the natural frequency of thecorrugated roller and the vibration mode.By using the model Type-3560-B-T15-Serial No2573185measurement instrumentof corrugated roller vibration displacement measurement, for single-sided corrugatedchance set the speed of44.9m/min and99.5m/min, the single-sided corrugatedmachine measure eight different location of the spectrum, compared with the theoreticalvalue of ANSYS analysis, Analysis of the corrugated roller is the main source of noisein corrugated machine， and sorted out the corrugated roller vibration test report. Theabove method choosing important five points of measurement,arrive at five point levelof noise，and it is concluded that the noise is low frequency noise, it mainly caused bydriving a manufacturing Error，With the gear frequency close to,Showed that the mainfactor was the tooth shape and surface roughness. To analyze the vibration of the singlemachine type, judgment source of vibration, vibration suppression measures, etc，it wasof great significance, And to provide evidence for corrugated roll damping noisereduction.On the damping materials, performance and structure and the finite elementsimulation of corrugated roller to calculate the axial and radial clearance designdamping ring, to reduce the vibration of the corrugated roller, this article used the discspring damper and damping ring, and corrugated roller multiple stepped shaft、corrugated roller roll shaft corrugated roll damping ring is optimized design, The overalldamping ring and circular arc transition throughout the single-sided corrugatedcorrugated roller machine stability was better. With the optimized corrugated machinenoise was measured, it was reduced19db optimization before.
