Vibration Performance

The take-up winder is an important equipment of chemical fiber textile machinery. Vibration performance is the key to decide quality and service life of product. The modal of winder is analyzed. It is shown that the rotation speed cannot be kept away from fifth and sixth resonance frequency. The Maximum stress response is calculated by harmonic analysis. According to results of high-cycle fatigue tests, the service life of winder is evaluated. The results show that there is the risk of fatigue damage for small damp ratio. Unlimited fatigue life can be obtained by creasing damp ratio. It can be concluded that creasing damp is an effective way to improve the service life.
