The leading branch of territorial-production complex of Russia — mechanical engineering. Companies of the industry throw dirt in the form of used organic solvents, toxic compounds of metals with waste galvanic and etching solutions, cutting fluids (coolant) and emulsions. you need to create complex regeneration treatment system of the most valuable components for these liquids. Reset electroplating and etching solutions can lead to the accumulation of heavy metals in the bio-organisms of the coastal zone and to enter them through the food chain to humans. To prevent contamination, a scheme neutralizing acid waste, accompanied by a reduction in the hazard class of the etching solution to IV class with the ability to accommodate long-term storage solid industrial waste in landfills.

In this paper the mathematical models of the main types of turning hydraulic engines, which at the present time widely used in the construction of handling systems of domestic and foreign mobile transport-technological machines wide functionality. They allow to take into consideration the most significant from the viewpoint of ensuring high technical-economic indicators of hydraulic efficiency criteria – minimum mass (weight), their volume and losses of power. On the basis of these mathematical models the problem of multicriterial constrained optimization of the constructive sizes of turning hydraulic engines are subject to complex constructive, strength and deformation limits. It allows you to develop the hydraulic engines in an optimized design which is required for the purpose of designing a comprehensive measure takes into account efficiency criteria. The multicriterial optimization problem is universal in nature, so when designing a turning hydraulic engines allows for one-, two — and three-criteria optimization without making any changes in the solution algorithm. This is a significant advantage for the development of universal software for the automation of design of mobile transport-technological machines.

Considered the issue of improving the operational characteristics of trailing scraper through the use of a combined knife system, which combines in one machine the widespread speed stab system and shovels cutting on. Requirements are formulated to knife scraper systems and the new combined knife system. It allows you to develop soil in terms of minimum energy and the free cutting of the soil. The practical possibility of obtaining a smooth face, more intense filling of the bucket, rational distribution of soil in the bucket in conditions of free cutting and filling of the bucket when the increased cutting depth of soil, without additional machines. The obtained data on the value of the coefficient of the specific resistance to cutting when the width of the free cut in the range of 1.0 to 2.2 m. The recommendations for a rational distribution of the soil in the bucket during the free cutting.

In order to manage the safety of work of operators of self-propelled transport machines (STM) proposed a security model of STM in the form of a two-unit probabilistic model, which allows for semi-optimum parameters of the speed limit and to increase the reliability of protection of workers through the use of the proposed technical device.

The presented method of calculation of the separation of polydisperse condensed moisture from a flow of wet steam or air in a vertical cyclone with tangential inlet side of the flow of the working fluid, and histograms of the size distribution is not deposited drops and diagrams of the distribution on the inner wall surface of the cyclone mass flow of the precipitated liquid. It includes gas-dynamic model of the motion of the gas and liquid phases of the working fluid inside the cyclone and the approach implements the idea of spatial and fractional discretization of the separation process. On the basis of calculations of the kinematics of condensed moisture specific cyclones have shown the feasibility of improving the accepted system of dehumidification that is associated with the implementation of intermediate wicking devices, their rational placement on the surface of the shell and setting the optimum constructive sizes.

In this paper we consider the question of Uzbekistan in promoting the development of international transport in supply chains. The development of transport infrastructure to ensure timely delivery of goods is one of the main tasks in supply chain management. The aim is to study of the project network terminal unitized cargo Uzbekistan in supply chains. Methods the study is based on analysis of existing methods and techniques of Russian scientists in the field of placement of objects. The method of searching the most rational location of logistics facility in the supply chain. Also pre-justified the project network terminal unitized cargo in Uzbekistan. Given the state of the problems and prospects of transport logistics of Uzbekistan, the developed method can be used by experts when performing the supporting calculations location of logistic objects.
