ANALYSIS OF IMPACT RESISTANCE OF CHAIN ACCORDING TO SPROCKET LUG PROFILE
DescriptionThe possibility of using involute sprockets, more technologically advanced in manufacturing, compared with sprockets with straight, convex-concave profile of the lug on the criterion shock resistance circuit, the maximum permissible speed of the drive sprocket for bush roller chain drives and gears with a toothed chain. The comparative analysis of researches of operation of roller and tooth chain gearings with various steps and types of profiles of sprockets showed that in all cases with increase in a step of a chain the coefficient of speed of blow increases, and the increase in number of lugs at sprockets reduces the speed of blow of the hinge about sprockets tooth. Value of coefficient of speed of blow for couple an evolvent sprockets - a gear chain is much less than value of coefficient of speed of blow for couple a plug-roller chain –sprockets of any profile. Less noise during the work of tooth chain gearings is due to evolvent sprockets. As a result of researches it is established that on kinetic energy of impact of sprockets and the hinge of a chain, sprockets with an evolvent profile can be applied on an equal basis with the sprockets having concave-convex or rectilinear profiles of lugs. Respectively, evolvent sprockets can be used both in chain transfers with roller and with gear chains

Description
Innovative tools of intercompany and strategic planning are designed to form interconnected tasks structural units of industrial enterprises and complexes in the sought after amount based on the cost of production of interdependent. Intercompany planning has no tools based on chain planning with cyclic calculations. Allocation of factors affecting business performance is a mandatory procedure in the development of innovative tools and intercompany strategic planning in industrial plants and complexes. Factors determining the efficiency of intercompany and strategic planning at industrial enterprises and complexes require detailed classification. The article examines the factors that determine the effectiveness of intercompany and strategic planning. The classification of factors, that are offered, which can form a conceptual framework of business development strategy for a long period of time, based on the use of interrelated production plans for the following criteria: conceptual, stabilization and functional. The developed classification of factors, which determines the efficiency of intercompany and strategic planning, allows us to: generate the concept of strategic business development; establish the optimum parameters of the structure and volume of internal and external supply, to determine the required size of lending and investment; achieve stabilization of interests of the economy and the level of investment attractiveness of the business, etc. Based on it, becomes possible to develop a methodology and logical approach to the formation of innovative tools intercompany and strategic planning at industrial enterprises (complexes)

Description
In recent years, Russia has paid great attention to the theoretical and practical aspects of conservation. Since electric drives consume about 70% of electrici-ty generated, the most substantial savings achieved by using variable speed drives AC and DC. In this article, for the positional DC drive with speed-dependent resistance torque we have developed three energy-saving diagrams for large movements: with a speed limit of the drive; restricted maximum current anchor chain and speed electric motor; restricted maximum and minimum values of the current anchor chain of the motor and the speed of the drive. We have developed software to determine the parameters of energy saving diagrams for large movements of the executive body of the electric DC depending on the speed torque resistance. For the considered energy saving diagrams, which provide large movement of the executive body of the electric DC, depending on the speed of the moment of resistance, it is necessary to provide the following condition – the maximum speed of the executive body of the drive must be equal to the maximum allowable speed value. We have also defined analytical dependences, allowing calculating the consumption of the electric power drive by moving its executive body, in accordance with the proposed diagrams. Realization of the developed positional control DC motor with speed-dependent torque resistance will lead to energy savings

Description
The article considers discrete automatic machines with memory, designed for searching the values of parameters of the system optimizing a merit figure of the system, described by some criterion function. The problem of multiple parameter optimization is shown as a problem of discrete optimization by means of representation of values of parameters of the optimized system in the form of a set of discrete values with a specified step of digitization
