The paper analyzes the reasons for large deviations in the ovality of the drums in the Design Regulations for Chemical Rotary Kilns in the check and calculation results,and establishes a dual-contact finite element simulation model that includes drum,cylinder(including backing plate),and supporting rollers.The influence of temperature rise on the mechanical properties of the cylinder material and the gap between the drum and the cylinder under cold state are considered.It aims to solve the radial deformation of the drum on the simulation platform of ANSYS Workbench,and combine the characteristics of the deformed contour to derive an algorithm for drum ovality in graphics,hence implementing it in the LabVIEW programming environment.The results show that the maximum radial deformation under the dual contact model does not occur at the quadrant points,and the contact state between the inner wall of the drum and the cylinder enhances the overall stiffness,which provides theoretical support for the optimization of the drums in engineering design.
