Abstract
The article substantiates the necessity of taking into account the complex influence of temperature and mechanical loads on the power plant elements, which largely determine the reliability and durability of their criterion parts. The prospects of practical application of thermoelastic analysis methods for the evaluation of temperature parts of machines and mechanisms are described. It is suggested that it is possible to implement a method of controlling temperature parameters caused by thermoelastic effect taking into account the sensitivity and resolution of modern thermal imaging equipment. The relation of thermoelastic analysis, which allows estimating the value of dynamic temperature loads of power plant elements, is obtained. The necessity of taking into account the simultaneous influence of interrelated thermal and mechanical loads on the parts of power plants is proved. Mathematical description of heat- and mass transfer processes of oil film between piston seal of internal combustion engine and inner surface of cylinder liner, which need to be taken into account when designing power units, is given. The presented results of theoretical and experimental researches create a basis for performance of the analysis of oil film evaporation processes change defining dynamic loading of critical parts of power installations. As a result, there is an opportunity to increase the reliability and efficiency of power plant durability operation by analyzing and recording the parameters of dynamic temperature stresses.
