“…An engineering analysis of the proposed design was performed using APM WinMachine, which made it possible to design the tool with high quality and make functional decisions based on a comprehensive engineering analysis. In [9], designs of broaches have been developed that will reduce the pulling forces and vibrations, as well as the specific pressure on the broach teeth. It is noted that the developed design of the tool helps to increase the durability of broaches, the quality of processing, saving tool material and economic efficiency.…”

A method for simultaneous processing of stepped holes in the bedding of a submersible pump and the boring bar design is proposed. The results of the study of existing methods for processing stepped holes and the design of boring tools are presented. It was revealed that the considered methods and designs of tools cannot be used for processing stepped holes in the submersible pump frame. The calculation of the developed design of the boring bar for static stiffness and strength, as well as the calculation of the stress-strain state (SSS) of the cutting plates by the finite element method using the ANSYS program, was carried out. The purpose of calculating the boring bar for static stiffness is a finite element study of the radial displacement of the boring bar cutter plates in the process of machining a stepped hole. As a result, the value of deformation in the axial and radial directions, which occur at the top of the cutting plate, is established. Also, the values of the cantilever overhang of the boring cutters are established, under which the conditions for the static rigidity of the boring bar are met. Taking into account the obtained results, the boring bar design was optimized.

“…In order to conduct experimental studies in order to confirm the results of theoretical calculations, a prototype of a half-tracked propulsor was made. Progressive processing methods were used for the manufacture of parts and components of the propulsor [6,7,8,9,10]. The improvement of the manufacturing technology of parts plays an important role in increasing the efficiency of use and prolonging the operational period of transport equipment.…”

Practice shows that with insufficiently high traction qualities of traction vehicles deteriorate its operational properties. At present, extensive research is under way at home and abroad to find inexpensive but highly effective ways and techniques to improve the traction qualities of vehicles. The design of running systems with reduced resistance to movement and slipping will help to significantly increase the productivity of vehicles and reduce fuel consumption. This, in turn, will contribute to greater operational efficiency for traction vehicles. The authors of this study have developed the design of a traction vehicle with a half-tracked propulsor. The objective of the study is to develop a mathematical model for calculating the efficiency of operating a traction vehicle equipped with a half-tracked propulsior with rubber tracks. The proposed mathematical expression takes into account the deformability of the rubber tracks of the propulsor, the uneven distribution of normal pressure along the length of the track, slipping, geometric parameters of the propulsor and the physical and mechanical properties of the soil. Using numerical methods, calculations were carried out to determine the effect of the tangential tractive force on the slipping of a wheeled traction vehicle with a different layout of the running system. The dependences of the amount of slipping on the tangential thrust force are determined. It has been found that with an increase in the traction force, the slipping increases, however, the intensity of growth of a half-tracked propulsor compared to a wheeled propulsor is much lower.
