in modern conditions become widespread trenchless methods for the construction of pipelines. The positive features of their use include increased speed pipeline installation, reducing the volume of excavation, etc. Existing regulatory documents limit the bending of the pipe at low temperatures need to be tested in terms of their applicability to new grades of polyethylene. The aim of this study was to determine the minimum permissible bending radius of the track, the passage of which in the conditions of negative temperatures polyethylene pipes PE80 would maintain its strength characteristics. By using a mathematical model dependency of the elastic modulus and yield point are calculated from the temperature stresses in the walls of pipes of different diameters in bending under different temperatures. In order to establish empirical relationships voltage on the pipe diameter and the radius of its bend procedure is carried out function approximation method of least squares. Presented obtained graphic dependences. Using the values ​​of the yield strength of the material at different temperatures were calculated bending radius of all dimensions. If the production of the track plow trenchless pipe-layer will be considered given the conditions, you will be provided with the necessary conditions for installation.

The phenomenon of buckling under the creep of concrete arches was investigated. Solution of the problem carried out by means of the finite element method. To analyze the stability we used Newton-Raphson method. It has been established that there is a long-term critical load, beyond which the growth of the deflection has not fading character. As the equation of the relationship between the creep deformation and strains we used viscoelastoplastic hereditary model of aging concrete. To determine the creep strain we used a linear approximation with respect to time. It was found that the long critical load for considered arch was in 1.44 times lower than the instant critical load.

In this paper we propose mathematical model of salient-pole synchronous generator of mini-CHP. The model is based on a full Park-Gorev differential equation. The saturation of the machine is taken by using the method of partial magnetic characteristics. This method allows most accurate evaluation of the change of parameters of an equivalent circuit of the generator in the absence of information about the magnetic properties of the machine. The model is Implemented in Simulink. Application of the model is possible when calculating the steady-state and transients in distribution electrical net wich contains salient pole synchronous generators.

The paper presents the results of a study on the influence of seasonal conditions on the reliability of diesel and gas diesel vehicles. During the experiment were treated with statistical data on the failure of the two groups of trucks, methane-diesel and diesel operated under the same conditions. As a result of analysis found seasonal variations in the flow of failures between the two groups. Then the failures were divided into failures of components and assemblies cars such as engine, transmission gear and chassis of cars. This division has revealed the influence of seasonal conditions on the reliability of components and assemblies of diesel and gas diesel cars and their differences. Studies have shown the need for adjustment of norm in the planning of maintenance and procurement of spare parts for gas diesel vehicles.
