Abstract

The ways of the effectiveness rise of the methods used for vibration investigation of the engineering structures with complex shape, subjected to dynamic and static loads as well as the temperature fields, are considered. The complexity of geometric shape, manufacture technology, and loads makes necessary the use of complete 3D problem statemennt of tjhe theory of elasticity in order to determine the most dangerous zones of stress localization. To create the general technique of analysis of the dynamic behaviour and stress state of such structures, it is required that the FEM, procedure of the analysis in parts and utilization of all geometric and physical peculiarities of the object being studied, be employed. The concrete implementation of these techniques, allowing significant simplification of the complex problem solution, is describbed To illustrate it, the results of the displacement and stress field computation in the elements of modern turbomachines are presented
