Description
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

ANALYSIS OF PROCESS OF DESTRUCTION OF ROCKS WITH A CHISEL АT DRILLING OF BORE HOLES
DescriptionТhe 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

MODELS AND METHODS OF CONTROL SYSTEMS OF ECOLOGICAL SAFETY OF FOUNDRY MANUFACTURE
DescriptionThe 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

OPTIMIZATION OF PARAMETERS OF AUTOMATED CONTROL SYSTEM OF CULTIVATION OF PINE PLANTINGS
DescriptionIn 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
