Theoretical and practical significance: based on the analysis of the methods of user actions using resources, a test demo implementation of one of the methods for analyzing users was carried out and other methods were considered that can give more information about the activity of users of web resources. The use of the developed toolkit allows you to optimize the interface of the ...

Based on the OBE concept and promoting education with science, this paper organically combines the drilling innovative test in metal processing with the mechanical professional knowledge, and expounds in detail the application of four-way piezoelectric drilling dynamometer in the transverse cutting vibration test of drill bit through the design of simulation test platform.

The paper analyses the results of studies of adhesive strength in the field of polymer coatings and nanocarbon components. As a result of research, it was found that coatings based on ultrahigh molecular weight polyethylene (UHMWPE) have the highest adhesion rates.

Bionic solution for reinforcement of “travelling column” machine is developed. It concerns special project of old heavy precise machine redesign and renovation. It is proposed to attach tree-like polymer-concrete outer bandage to the flexible column. Bionic-shape vertical console is created. Design is proved by FEA simulation. Static rigidity is increased twice. Bending eigenmode ...

This paper discusses the technology of multilayer knitted material for the upper of footwear for outdoor activities. A feature of this technology is that each layer of the resulting material is responsible for certain functions.

FEA simulation of the huge indexing table for a multi-purpose machine tool is provided. Excessive corner flexibility of the initial design is revealed. A set of reinforcing design solutions is generated. Several combinations of cast iron ribs and polymer concrete inserts are analyzed. Corner rigidity is enhanced from 48.8 to 388.5 N/μm with table weight rising from 5.36 to 6.98 ...

In this paper, the machinability of cast iron is considered. Cast iron is an alloy of iron with carbon (and other elements), in which the carbon content is at least 2.14 % (the point of ultimate solubility of carbon in austenite in the diagram of states), and alloys with a carbon content of less than 2.14 % are called steel.In our work, special attention is paid to the machinability ...

This paper presents the results of comparative investigations of the efficiency of the process of magnetic-abrasive processing (MAP) of metal using various ferromagnetic abrasive powder materials. It is shown that diffusion-borated iron-based powders provided an increase in the productivity of the MAP processing. In addition, the new powders showed a higher service life compared ...

This work presents the results of studies aimed at obtaining ceramic materials for thermal units operating in a nonstationary thermal field based on cordierite and wollastonite ceramics using domestic raw materials. The research results can be used for the production of ceramic fuels based on wollastonite and cordierite using natural and man-made raw materials.

Many scientists are engaged in the study of theoretical problems associated with the creation of self-propelled multi-drive multi-axle wheeled vehicles of increased crosscountry capability. Basically, these studies are carried out in relation to machines with mechanical transmissions. Thanks to the results obtained, a fairly developed segment of allterrain vehicles, including ...
