Dynamic Balance Optimisation for the Middle Shaft System of a Cotton Comber

For the vibration problem of a cotton comber, a model of the middle shaft system of a head-stock was built using SOLIDWORKS software. It was found that the vibration was mainly caused by the shifting of the centroid. Then a dynamic optimisation model was established according to the dynamic balancing theory using the revolving method. The installment of the middle shaft system was optimised using ADAMS software with the aim of minimising its counterforce. The optimal value of the flange plate and timing regulation plan are given correspondingly. The results show that the noise and vibration of the comber CM500 are decreased significantly. Key words: cotton comber, dynamic balance design, parameterization design, ADAMS. imbalance. If the mass distribution of each component is in a different plane, the force system composed of the centrif-ugal force is not intersected in the same plane, but there is a space force syste
