It is proposed to determine the optimal diameter of the grinding wheel for sharpening shaped disk modular cutters by 3D modeling of the grinding operation, taking into account the restrictions on the formation of a saddle on a sharpened tooth and grooves on an adjacent tooth. Analysis of the results of modeling the sharpening operation of standard cutters with a modulus of m = ...

This article examines the documentation of medical records on electronic media and suggests the formalization and documentation of medical data in the medical information system for maintaining an electronic medical history. The basic technologies and interface for documenting medical records, the formation of electronic templates for standardization, the design of electronic ...

The analysis of the efficiency of work of self-propelled mine cars as part of tunneling complexes is carried out. Perspective schemes of power supply of self-propelled mine cars, as well as ways of modernizing their wheel propellers are considered. The calculation of the parameters of the wheel propeller control system during the maneuvering of a selfpropelled mine car is performed.

In this paper, an X-ray diffractometer is used to determine the residual stress of the lower end of the steel ring at the joint surface of the rim lock ring groove. Analyze the distribution of residual stress on the lower end surface of the steel ring before and after shot peening, and perform a finite element model simulation analysis on the lower end of the steel ring based on ...

As the representative of the third generation of new wide band gap semiconductors, SiC has excellent physical, chemical and electrical properties.In the field of power semiconductor, especially in high power, high voltage and some special environments, it has a good application prospect.In this paper, some of its physical properties are introduced, and then the growth method and ...

The WRF model hasmany characteristics such as easy aintenance,portability,and high efficiency.The "8.02" rainstorm was simulated with WRF mode.It was found that although the WRF model can simulate the location of precipitation in northeast China, the intensity is obviously stronger.And the precipitation in the North China area, whether from the precipitation area or the intensity, ...

The developed and implemented mathematical models and algorithms are briefly described.

This work gives an example of additional soil protection at the foundation of the viaduct and describes the technology of this protection.

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 ...

The task of current importance in mechanical engineering and repair productionis to further increase the reliability and durability of mechanisms and machines by increasing wear resistance of details. One of the ways to solve this problem is to apply a coating of selffluxing materials by the gas-flame method, followed by induction flashing with quenching from the liquid. This ...
