Stress Strain State

The method of the gas turbine engine impeller forced vibration and stress-strain state parameters calculation is given. Using the finite element method, a refined mathematical model was developed for the several types of impellers most widespread in the practice of gas turbine engines building. The developed mathematical model takes into consideration the impeller blades geometric parameters and the construction of blades connectors. The results of its forced vibration frequencies calculation, caused by the influence of non-stationary gas flow are given for different types of the blades connectors. The dependencies of the impeller blades stress-strain state from the value its feather geometric perameters have been studied too.

As the title implies the article deals with the problem of stress-strain assessment of metallic elements in power-generating equipment. An electromagnetic-acoustical method is proposed to test and diagnose the technical condition of power apparatuses. It is stressed that the transfer function is an integral parameter that makes it possible to assess the condition of metal in a unit under test. The studies established the relationship between the quantitative values of polynomial roots of the transfer function in the system “a unit under test - electromagnetic acoustic transducer” and the level of the stress-strain state of metal.
