Transverse Vibration of Axially Accelerating Moving Fabric:Experiment and Analysis

摘要：

　　Axially moving fabric can be met in many textile devices.In most cases, the transverse vibrations of fabric can cause a series of negative influents to the product.In this paper, the transverse vibration of axially accelerating moving fabric, which is excited by velocity fluctuations, is investigated by experimental method.The harmonic varying velocity is achieved through a brushless DC motor controlled by PWM technology based on the embedded microcontroller LPC1768.An inductive non-contact displacement sensor is used to measure transversal vibration of fabric.The motor speed is measured by a photoelectric encoder.The experimental data is processed by measurement platform based on Labview and the analysis is given.Laboratory measurements demonstrate the effect of velocity fluctuations on transverse vibration of fabric, particularly near the parametric resonance region.
