Abstract:

With regard to the vibration and noise problems of CM500 cotton comber, a CAD model of the middle shaft system of headstock is built by 3-D software of Solidworks, and it is found that eccentricity exists with the mass distribution of the system, which generates centrifugal force, and results in vibration. For this reason, a dynamic model of the middle shaft is established according to the theory of dynamic balance and revolving method. The installation positions of some parts on the plan are optimized by software of ADAMS. The minimization of the bearing reaction about the middle system is fixed as the aim of optimization, it changes the mass center positions of flange plate and timing and regulation plate so that the amplitude of its bearing reaction is significantly reduced. Thus, its noise and vibration are decreased and its dynamic characteristics are improved.
