Methods of jet pneumatic automatics as applied (Pneumatic automation) to systems of transportation on an air pillow are considered. Use of methods pneumatic automation is shown at designing the flowing channels providing jet management on the basis of aero hydrodynamic effects. On the basis of hydro dynamical calculation parities for definition in engineering calculations of critical values of characteristics of flowing elements of the pneumoconveyor are determined. Time of transient of system of switching of air streams is determined
In this article, the mathematical model of management of interaction of working body of the cutter with branches of trees is submitted. Optimization of design data of the machine for scrap of trees is executed
Тhe physical processes, arising on a face at interaction of a chisel with rocks are considered. The mathemati-cal description of model of mechanical speed of drill-ing in a function from speed of rotation, twisting mo-ment, diameter of a chisel and properties of destroyed rocks is executed
The article presents a mathematical model of the interaction of vibration control the working body of the roots carver with soil and plant roots to optimize the design parameters roots carver
The experimental data of the study of physical and mechanical properties of nanomodified "poor" concrete for road clothing base creation is presented in this article
Science-based possibility of use of the concentrate, based on lactoserum, aimed to adapt protein and carbohydrate components in meat technology is shown
The features of landslide soil interaction with piles of single-row retaining constructions, taking into account the influence of anchor piles are considered
In the article, the use of ferment way-polysaccharide fraction (WPF) in manufacture of bakeries as a com-ponent, which possesses high medical and biologic characteristics, is described; but it also influences a “force of flour” and a quality of protein of a flour
The given developments are devoted to modeling of control systems by ecological safety of foundry manufacture. In a working zone of foundry shops except for a dust the significant amount of polluting substances is allocated. The most unsuccessful sites from a position of allocation of a dust are chambers and lattices. The experimental analysis shows, that in structure of a dust the weight maintenance of fractions with a diameter up to 20 microns reaches 43,8 % on weight. The given dust is most dangerous to health of the working personnel and creates problems when clearing the air
In the article, the opportunity of increase of efficiency of automated control system of cultivation of pine plantings by means of optimization of modes and parameters of cleaning cutting of forestry is considered. The regression equations for definition of parameters of growth of trees are received. The criterion of optimization of cleaning cutting in pine plantings is allocated. The increase of the forest yield and reduction in age of technical maturity of trees is shown, with a help of automated control system
