Finite element solution to the problem of large-area multi-body contact between cylinder and roller

Cylinder;  multi-body contact;  Contact pseudo-unit;  Substructure

Aiming at the characteristics of large-area multi-body contact and strong structural repeatability between cylinder and roller, the multi-body contact model of cylinder and roller is established by applying contact pseudo-unit and substructure technology, and the load caused by the weight of the kiln skin and lifting plate is automatically converted into the volume of its action area by defining the equivalent density, which reduces the workload of load processing. The numerical calculation results of the multi-body contact problem between the cylinder and the roller show that the pressure of the cylinder shell in the gear section is much greater than that of the cylinder shell of the cylinder segment, the strength of the cylinder shell of the gear section is weak, and the strength of the cylinder shell of the cylinder segment is somewhat surplus.
