Damping experimental research for the beam of computerized embroidery machine

Considering the fact that beam vibration of the computerized embroidery machine affects directly the embroidery quality and the broken end ratio,the beam damping equipment is designed based on the study of the beam damping.The vibration test is marked in different velocities to probe the effective way of the beam damping by changing the fixed type of the beam on two ends,setting up the curve beam with right angle to sustain the beam,and installing the rubber damper,so as to reduce the amplitude of the beam vibration.The critical rotary speeds of the beam under horizontal and vertical bending vibration are figured out by experimental research.It is found that the above measures can effectively reduce the amplitude of the beam under horizontal and vertical bending vibration.
