Rigid Flexible Coupling Dynamics Research of the Flap Transmission Mechanism with Clearance Joints
Published 2023-06-01“…The dynamic output angular velocity and angular acceleration of the flap transmission exhibit obvious oscillation, and the amplitude of the angular acceleration is larger than that of the angular velocity oscillation; at the same time, when the driving load changes, the angular velocity and angular acceleration fluctuate greatly, but the fluctuation degree in the case of<italic> c</italic>=0 is greater than that with clearance; in addition, the higher the friction coefficient at the clearance joint is, the greater the amplitude of angular velocity and angular acceleration oscillation are, accompanied by high-frequency oscillation and delay phenomenon.…”

CALCULATION AND SIMULATION OF THE CLEARANCE FOR FLEXIBLE HIGH-SPEED BEATING-UP SYSTEM CONSIDERING RESISTANCE EFFECT
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. …”

Analysis of Factors Affecting Lubrication Performance of Crankshaft Main Bearing Considering Thermal Effect
Published 2022-10-01“…The calculation results show that the thermal effect has a great influence on the crankshaft main bearing. When the external load of the bearing increases, the maximum oil film pressure, minimum oil film thickness and maximum friction power loss will increase; when the bearing clearance becomes smaller, the maximum oil film pressure decreases and the bearing temperature increases; when the oil inlet temperature increases, the maximum oil film pressure increases, the minimum oil film thickness decreases and the maximum friction power loss decreases.…”
