Simulation analysis of the dynamic characteristics of a standard section of an air cushion belt conveyor based on fluid-solid coupling

Aiming at the influencing factors of the dynamic characteristics of the flow field in the air cushion belt conveyor under the condition of high speed and heavy load, the key part of the air cushion belt conveyor, the standard section, is simulated and analyzed, the theoretical derivation of the air cushion pressure is carried out by using the principle of force equilibrium to get the theoretical expression of the air cushion pressure and the theoretical distribution curve diagram, and the coupling relation between the conveyor belt and the air cushion flow field is simulated and analyzed by using the coupling analysis module of ANSYS. The results show that the increase in the number of rows of air holes and the aperture of air holes will increase the high-pressure distribution and stability of the air cushion flow field to a certain extent, and the staggered distribution of holes is better than the parallel distribution of holes, and the deformation of the conveyor belt will affect the distribution of the air cushion pressure to a certain extent.
