Semitrailer Roll Stability Support system is considered for the purpose of liquidation roll-over risk. In some cases this system can't give a full guarantee of roll-over prevention. Therefore the problem of decreasing roll-over risk is set. The author offers to improve Roll Stability Support system and to decrease roll-over risk by using adjustment air suspension with pneumatic cushions with discrete commutation.The further research problem includes careful analysis of system, simulation and carrying out an experiment in laboratory.

The article deals with the conditions of maintaining the quality of operation of hydraulic drive when it is used for its intended purpose. Quality of service is determined mainly by keeping the parameters of operational properties of the hydraulic fluid within the permissible limits of the technical documentation. Examined the effect of viscosity and acid number and impurities (solid, gaseous and liquid) for operating and properties of the hydraulic fluid. A scheme of periodic and necessary cleaning and updating the hydraulic fluid without stopping the hydraulic drive is purposed.

The article describes the experience of the verification of CFD modeling of fluid flow in the wet part of centrifugal pump type AH. Verification was carried out by comparing the characteristics of the pump, obtained by physical experiment (normal trials) and by numerical simulation software package STAR CCM + in the entire range of capacities. A comparative analysis of theoretical and experimental data allowed to draw conclusions about the adequacy of mathematical models of flow used in numerical simulation. The discrepancy between the experimental data and calculations for the curve H-Q is not exceeded 6% (theoretically calculated head is somewhat higher), which can be attributed to some deviation of the real form of the wet part of the 3D-model, in particular, due to defects in the impeller and the volute.

The working characteristics of the ion source with azimuth electron drift “IS-200” was investigated. It was shown that the ion source has two discharge modes: thruster mode and magnetron mode. The thruster mode is characterized with high voltage and high current efficiency with low discharge current. The increased ion current with low voltage and ion current efficiency are in magnetron mode. The thruster mode is more preferable for ion-beam processing. The optimal parameters of the ion source functioning was determined by the current-voltage characteristics.

A distinctive feature of this algorithm is a multiresolution image processing. The identification of the pixels is based on the correlation criterion with respect to the mask size of 11x11. Created stereo system allows to register three-dimensional images with the frame rate to 10 Hz for stereomate’s images size of 320x240 pixels. Such systems are demanded mostly in industry, automation, robotics and medicine. It’s possible to increase the speed of the system by creating a more efficient algorithm.
