The bending of threelayer elastic beam partial support pattern on the elastic basis with stepped variable thickness of one of two stiff shells is considered. To describe kinematics of asymmetrical over thickness core pack the hypotheses of the broken normal are accepted. A system of equilibrium equations in terms of displacements has been derived. Analytical deciding a problem are received and their numeric analysis are conducted.

In article the problem of determining the carrying capacity for perfect ring composite blades, zestkoplasticesk selfsupporting arm chewed up by internal and external edges and under the influence of lateral loads evenly distributed. It is shown that the surface of the disc is divided into five doughnut zones, each of which implements a variety of plastic. Sets a static field and kinematic Paul velocity deflections, found the equation for unknown radii between various plastic zone, as well as the equation to determine the basic reaction and load limits.

The method of vibrating diagnostics offered in given work, is based on harmonious excitation of turbomachinery blades and definition of the dynamic response in some point. The used equipment of vibrating excitation influences investigated object the concentrated force, or creates kinematic excitation. In this connection the special attention is given equivalent weights of an elastic body with parametre of excitation «kinematic». Considering features of the used vibrating measuring equipment, as supervision parametre vibrating moving and vibrating pressure here are considered.
