A Computational-Experimental Method for Determination of the Stress-Strain State of Thermally-Loaded Power Equipment according to Full-Scale Strain-Gauging Data

摘要

A method for construction of a monitoring system of the stress-strain state of power equipment based on the functional relations and regression dependences of the stress state on measured parameters is considered. An algorithm for construction of a monitoring system of the stress-strain stress for the elements of equipment subject to the nonstationary actions of a heat carrier with a variable temperature is presented. The results of use of this algorithm to study the stress-strain state of the connecting pipes of shell elements of power plants under operational conditions are given.
