Abstract
According to the high iterative feature of shell and tyre structure, the multi-level substructure technique is adopted to set up the multi-body contact model between tyres and long shell. Applying parametric quadratic programming method, the multi-body contact FEM analysis of the No.2 rotary kiln in Henan Branch of China Aluminum Company is done, and the conclusions are as follows: The equivalent stress of shell at supports changes 5 times, and at other parts changes 4 times; the strength of shell at supports is weak, and at other parts is affluent; the strength of shell at the supports 2 and 3 is the weakest.
