Sažetak
This paper presents an analysis of the stress distribution on the outer surface of the riding ring of rotary cement kiln during working cycle using both the theory and finite element simulation. In the theoretical analysis, the total stress is obtained as a combination of bending, thermal and contact stresses. To obtain bending stress the kiln is considered as a simply supported, indeterminate beam subjected to static and symmetrical loads and Castigliano’s theorem is employed. Thermal stresses are obtained assuming both linear and non-linear temperature distribution over the ring thickness. Contact stress between ring and supporting rollers is obtained using Hertz contact theory. Bending, thermal and contact stresses are also obtained numerically in separate simulations, mimicking conditions assumed in the theoretical part. All results are in excellent agreement. In addition, a more realistic ring model subjected to all loads simultaneously is also simulated. These results showed slight disagreement with theory in the contact region, mainly due to sliding contact between the roller and the ring, but overall agreement was good.
