Belt conveyors are widely used in factories of building materials. They are used to transport bulk and General cargo on the short, medium and long расстояния.Установка the working body of the screw conveyor brushes allows to increase capacity of the conveyor by eliminating the accumulation of the material to be transported inside the gutter.

The task of identification of defects in rods with different variants of fastening. In the basis of lies method parameter identification based on an analysis of the frequencies and parameters of natural modes of the structure. Built model of the rod design has defects fluctuations, using finite element of the complex 

Keywords: Defect, damage, rod, the oscillations of the cantilever rod

Defined criteria for identification of defect parameters, on the basis of the analysis of the different modes of own fluctuations, with the use of finite element modal calculation console corpulent model of a rod with a single defect. Developed finite element model of a universal complex . Considered corpulent (3-d) model on the basis of 3D finite element Solid92. When solving the problem considered on 26 oscillation modes depending on the size of the defect and its location.

Cracking of reinforced-concrete elements with holes is examined. Comparison of theoretical and experiment moments of crack’s  formation during torsion, and during intensive torsion with twist. Formula for practical calculations of cracking of reinforced-concrete elements with holes during torsion and formula for estimate of cracking of reinforced-concrete elements with holes during intensive torsion with twist is suggested.
