The purpose of the article is to develop methods for hydraulic design of extreme discharges and water depths in critical gage lines of waterways diverting water from spillways for the accepted law to regulate linearly distributed releases of stored water discharges. The task of control for linearly distributed releases of stored water discharges is based on hydraulic design for the process of propagation and transformation of long waves described with Saint Venant equations. These equations are nonlinear and have no accurate solution in general case. To get approximate solutions they are linearized. It is established that the task of integration for these equations supposes to get their preliminary solution in the form of complete integral. Applying the complete integral theory we get analytical solution that describe the process of transformation for one direction waves moving in infinitely long prism canal of semi-bounded extent with initial uniform regime of water flow. An example of changes in both water discharge and flow depths in two fixed downstream gage lines of hydraulic works at the distance of 5000 and 10000 m from the initial gage line is presented. Hydraulic design was carried out according to the derived analytical formulas accepted as an example classical method of characteristics that is considered as analogous. Comparison of the design results on two methods allowed to determine the maximum relative error that does not exceeds 3,5 % for the design discharges and water depths. Introduction of the developed method for hydraulic design of linearly distributed releases of discharges in waterways diverting water from spillways will make it possible to optimize idle and non-technological stored water discharges

The aim of the article is theoretical and experi¬mental confirmation of the possibility to improve the acceleration performance of tractor units by in¬stalling a tow hitch with variable stiffness. Application of speed tractors in agricultural pro¬duction meets a number of difficulties associated with the unsteady processes, especially while accel¬erating of machine and tractor units. The resulting large inertial loads during acceleration lead to loss of engine power, due to which the machine and tractor unit operates with less performance and economy. Our analysis of published studies shows that the acceleration performance of tractor units is greatly influenced by the rigidity of external links in the form of coupling devices installed between the trac¬tor and the agricultural machine. The design of the tow hitch with variable nonlinear stiffness for class 1.4 tractors is offered. The results of theoretical and experimental studies on the effect of the proposed tow hitch with variable nonlinear stiffness on the acceleration capabilities of machine and tractor units based on class 1.4 tractor are shown. Based on the analysis of characteristics obtained by the analytical and experimental ways, it was proved that the use of the hitch with a variable non-linear stiffness on class 1.4 tractor helps to improve the acceleration performance of the machine and tractor unit
Analytical research results of contact forces of interaction of concentrated forages components’ particles in their movement in relative screw drums are presented. It is shown that contact forces – the most difficult forces by their nature; result from stochastic (probable) collision of bulks particles and in particular of concentrated forages components’ particles. Therefore the main objective of this modeling – to describe the stochastic phenomena of the so-called conditional contacts of particles for which some assumptions are accepted, for example, in forcing of mass of concentrated forages components’ particles by the walls of the rotating relative screw drum in the radial direction there will simultaneously arise contacts caused by geometry of a screw drum, i.e. the property of its walls is pressure transfer in relation to the mass of particles in the direction of the modeled movement. Schemes of engagement of concentrated forages components’ particles contacting in the relative screw drum, the probable schedule of sliding speeds values change in their consecutive contacting, their density distribution are demonstrated
Ozonization of incubation eggs when storing at an egg-storehouse is well included in technological process of production and egg sorting. Ozone influences absolutely all known viruses and microbes. Larger chickens are hatched from ozone-treated eggs, safety of chickens is increased. However, the present technology did not obtain the wide spreading in the sphere of poultry farming because of uneven concentration due to the volume of treated premises. In the result of mathematical modeling there was worked out the system of management with electrical and technological process of ozonization of egg-storehouses of poultry factories, indexes of quality the work of which was assessed in the system of automated projecting of logical-dynamic systems SimInTech. The summarized integral mean-square index (J = 9,7%) decreased on 19,3 % in comparison with the variant without regulation (J = 29%), that testifies on enough qualitative regulation of distribution of ozone concentration in an egg-storehouse and satisfies the shown acceptable value of the present index (no more 15%). On the basis of produced researches there was created the nomogram determining the tension of charging facility and discharge of a ventilator of electric ozonator in dependence on treated egg amount. In accordance with technical solutions there was worked out the principal electric circuit with system of electric equipment of electric technological process of ozonization of egg-storehouses of poultry factories on the basis of microcontroller ATmega8
