For a more complete use of information in geodetic measurements of rotary kiln geometric parameters, a method of mathematic simulation of the stress state in the kiln shell is proposed. The essence of the calculation method is to ascertain the stress-strain state of the kiln shell as an elastic statically indeterminate multi-span beam. The disclosure of static uncertainty is performed by the displacement method, which allows to unify the calculation algorithm for kilns with an unrestricted number of intermediate k...
