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

Resumo

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.
