Abstract: Rotary kilns are widely used in various industrial applications. Most rotary kiln cylinders are supported by three or more stalls. The force state of these rotary kiln cylinders is statically indeterminate, and the calculation process is correspondingly complicated. Aiming at simplifying the calculation model, the structure of the two-stall short kiln based on the design principle of "lateral rigidity and longitudinal flexibility" was designed. The finite element simulation model of the rotary kiln was established using SolidWorks software, and the mechanical behavior analysis of the cylinder was carried out by ANSYS software. The simulation results showed that the deflection value of the cylinder is larger in the vicinity of the kiln and the span, and the load at the bearing is more concentrated. The stress alternates in the rotary kiln body. The stress and strain of the middle area of the rotary kiln cylinder span are very large and close to the allowable stress. The simulation results provide a theoretical reference for the safety assessment and reinforcement design of the cement rotary kiln cylinder.
