This article discusses the possibility of improving the environmental situation by changing the percentage ratio of metal and fiberglass fittings produced in the direction of increasing the latter. A comparative analysis of the calculation of the slab basement of 300-mm thickness was carried out, in the construction of which reinforcement made of steel (class A-500C) - and fiberglass were used. The results of the study led to the conclusion that, due to the recycling of plastic waste to produce this innovative building material, there is great savings for the manufacturer, and to this is added an improvement in the environmental situation in general, as the amount of industrial waste on the globe decreases without using environmentally friendly methods. destruction.

The following work is concentrated on the analysis of dynamic pressure distribution of a brake pad by using ANSYS software. A non-linear contact analysis of brake disc has been performed using Finite Element Method. The finite element model of disc and pads have been developed, and followed by an inclusive simulation of the contact analysis of disc brake system using ANSYS software. A detailed finite element model of a disc brake assembly was developed. Contact analysis was done to determine the pressure distribution, interfacial contact area and normal contact forces under both frictionless (μ=0) and frictional braking conditions. The influence of varying friction coefficients and the brake hydraulic pressure on squeal occurrence is examined. The results illustrated that the contact pressure distribution and the magnitude of normal contact pressures are far greater towards the leading edge of the pads comparing to the trailing edge.

In this paper, the task of territorial planning of road transport enterprises is considered, taking into account modern requirements for the development of the urban environment. Methods for solving problems of territorial planning using geographic information technologies are highlighted. The work identified the factors of placement inherent in this subject area and characterized by spatial, temporal, pragmatic characteristics. Given the spatial nature of the task and the input data, it is proposed to use geoinformation modeling as an effective means of solving problems, which are based on geodata. The model of a geographic information system is presented as a combination of a model of visualization and consideration of spatial distribution factors, including sets of production rules. This model also contains a block of regulatory data that regulates the process of land use and allows us to evaluate the suitability of a particular site. The process of visual analysis is described and the main elements of the visualization model are identified. The totality of the data components of the geo-information model makes it possible to take into account heterogeneous information, conduct its complex analysis and make better decisions.

The issues of violations of the terms of delivery of goods on the railway network are considered. The main reasons for the violation of the delivery time are systematized on the example of the North Caucasian Railway. The North Caucasian Railway serves the ports of the Azov-Black Sea basin and the consignees of the Southern region. Over the past 10 years, the volume of loading of export cargoes to the ports of the Southern region has increased by more than 47%. Despite the relatively high reliability of cargo delivery, a negative trend in the increase in financial risks of the company RZD was noted. An analysis of the claim work was carried out, in connection with the violation of the delivery deadlines. The issues of speed and delivery of cargo and empty shipments at the North Caucasian Railway are considered. The main reasons for the arrival of goods with broken delivery dates were: the receipt of wagons with broken delivery dates at the joints of the road; Excessive availability of wagons to ports and port oil depots; an increase in the number of passenger trains in the summer. Mechanisms for managing the delivery time in rail transport on the basis of logistics and information technologies have been developed. Expansion of the zone of logistics management of railways traffic to ports based on the use of information systems that allow monitoring of operational work, identify problems of the road network, will reduce the load on the infrastructure of the port roads, fulfill all budgetary targets, and obtain additional profit.

The paper summarizes the analysis of a variety of foreign and national scientific publications focused on the topic in question. It explores the opportunities to use modular structures, especially three-dimensional modular units as a part of superstructure for building reconstruction. The point is made that the use of transforming three-dimensional modular units helps considerably reduce transport costs. Despite a number of drawbacks inherent in modular units, the use of three-dimensional counterparts is suggested to be viewed as one of the promising ways of accomplishing energy efficient reconstruction.

The article gives an overview of the ways to utilize the heat of the boiler exhaust gases. In conditions of actualization (both technical and economic expediency) of application of technologies for fuel economy and environmental protection, the use of aggregates based on the internal combustion engine and microturbines with the utilization of the heat of the cooling system and exhaust gases has found application. Deep cooling of combustion products of natural gas both in boilers (condensing boilers) and in special condensing heat exchangers (utilizers) makes it possible not only to organize the full utilization of the physical heat of the flue gases (the lowest heat of combustion of the fuel), but also to select the latent heat of condensation Water vapor. The coefficient of efficiency of the boiler-aggregate will be increased in this mode by 8-12%, provided that the boiler operates in the optimal mode. Cooling of combustion products also reduces the content of nitrogen oxides in flue gases, incl. With the use of heat pump plants. The efficiency of the implementation of projects for the installation of condensing heat exchangers depends to a large extent on the number of hours of operation at maximum capacity in the mode of deep utilization. In this connection, we propose a variant of optimization of the boiler room thermal scheme with the heat recovery of the flue gases.
