    CALCULATION AND SIMULATION OF THE CLEARANCE FOR FLEXIBLE HIGH-SPEED BEATING-UP SYSTEM CONSIDERING RESISTANCE EFFECT by QIU HaiFei

    Published 2022-01-01
    “…The results of contact dynamics simulation with different clearance states show that there are obvious differences between flexible body simulation and rigid body simulation, and the former can better reflect the real situation of beating-up; The clearance of 0.03 mm and 0.06 mm has a great influence on sley vibration which is not conducive to reduce vibration and noise for loom system; 0.09 mm clearance will not only cause high-frequency reaction force on main shaft bearing, but also aggravate contact and collision between crank and connecting rod; There are many overlaps between centroid trajectory of flexible main shaft with clearance and ideal trajectory, because of that, multi-point contact collision occurs in the crank bearing. …”
