The present cultivators of the soil have a negligible width and depth of loosening is mainly up to 0.6 m. When the number of racks is significantly reduced completeness of loosening, increases the mass of the gun and increase traction resistance. In addition, the possibility of loosening soil to a greater depth is limited. There are rippers with surround deformers. They are inclined relative to each other vertical knife rack, rigidly connected to each other in the lower part with shingles made V-shaped with the apex directed upwards. In this architecture, the system deformers there is a need for analysis to determine the tensile strength in a first approximation: as much as possible to lengthen the elements of the blade without loss of strength and significant changes in their geometric characteristics of the flat cross-section. Reviewed the formulation of the calculation of the strength of the isotropic sloping steel plates of finite dimensions, a polygonal profile with rigidly clamped opposite edges of constant cross section, equal stiffness, as an element of deformers of the chisel type surround. Shows the justification of the selected geometric characteristics of the broken plate. Presents a preliminary finite element modeling using the software - computing complex Structure CAD (SCAD), considering static and dynamic loads. In the formulation of the numerical calculation primarily pursued the goal of establishing the adequacy of a solid model of the stress – strain state of a polygonal sloping steel plates of constant cross section with rigid pinched at the edges. It is established that the threat is a reduction in the actual thickness of the plate more than 1/3 of the project, which leads to failure of the individual piece of details. With little loss of thickness plots of displacements is characteristic reflects a valid value.

This article describes the issues on the basis of scientific research and the data produced in-depth analysis of technical condition of water spending long maintained facilities for further classification of defects and damages, as well as the prediction of their remaining life. Mathematical and software was built on the length of the projected water filtration since the beginning of the construction survey. Program - technical complex in the survey predicts the loss of bearing capacity as the structure as a whole and its constituent elements from the moment of injury. In the future, software and hardware predicted time total loss bearing capacity of the construction, using various regression dependence. Technical possibilities of application systems allow calculation of the geometric characteristics of different defects and damages on the surface of structures, and in some of its elements. Presented Program - technical complex for solving the problem of forecasting residual resource of water conveyance structures can be used to create a database during the operation of these structures over a long period of operation that will extend the life cycle of water conveyance structures with regard to their reliability parameters. The basic provisions on the organization of determination and prediction of residual life long maintained water conveyance structures, identification of defects and damages, assessment of suitability taking into account the reliability of the parameters, for further use water conveyance facilities.
