Science

  • Database of mathematical models of defects in metal structures and recommendations for a combination of types of non-destructive testing was created. This is necessary for more accurate detection of defects in the power parts of the equipment, which allows to avoid the destruction of structures during operation.
  • Methods for ensuring the durability of power parts of forge-and-press machines and tools were developed. These methods allow to extend the service life of machines and tools for metal pressure treatment, to improve the quality of the resulting products by increasing the rigidity of structures, and, ultimately, to reduce the cost of production. This task was set for the first time, there are no analogues for this type of equipment and tools.
  • Methods for designing large-sized heavy-loaded structures for limited durability, including the reduction of local stresses in the basic parts of the presses were developed. This allows to design and manufacture equipment and tools with a strictly limited lifetime order program (which significantly reduces manufacturing costs).
  • Obtained 9 patents for inventions, which can be divided by subject into 2 groups. The first group refers to crank presses. Patents of this group:

The second group of patents relates to the determination of strength properties of mechanical engineering parts and ways to improve them:

Scientific interests

  • Use of magnetic properties of ferromagnetics to determine the resource of structures for various purposes.
  • Study of the influence of various factors (stresses, time variables, thermal cycling, tribo-fatigue, etc.) on the stability and durability of mechanical engineering parts.

The paper presents the results of the investigation of the change in the coercive force in the materials of the die tool working parts during manufacture and operation of die tools; the paper offers possibilities of application of testing based on the coercive force.

Possibilities of control of the level of accumulated damage in dies for cold and hot forming as a function of the coercivity are considered. The coercivity of the material of dies for hot forging and cold stamping is studied. Formulas are obtained for determining the coercivity in steels for hot die forging in the state as delivered.
Ivanov V.I., Kornilova A.V., Musatov V.V. Technical diagnostics in accident risk assessment// Inorganic Materials, Volume 52, Issue 15, 2016, P. 1509-1514.
For a comprehensive assessment of safety of hazardous facilities, an accident risk ratio is used. Existing methodologies of risk assessment do not account for technical conditions of the facility and the degree of its defectiveness. This work demonstrates the possibility and necessity of a broader use of nondestructive testing (NDT) and technical diagnostics (TD) to estimate the probability of an accident, formulates the requirements for analyzing the risk, and establishes the line of development for these approaches. We consider the issues related to introducing new requirements for NDT and TD, which deal with representing the quantitative values of NDT, i.e., reliable data on the size of defects and measurement errors. We prove the necessity of using the methods of probabilistic fracture mechanics for assessing the real values of accident probability.

Based on the representative sampling of experimental data and processing of the obtained results, a method of determination of the service life of the instrument for cold sheets is developed. The method is based on correlation between the magnetic, mechanical and physical-chemical (chemical composition, thermal processing mode, plastic deformation, micro- and macrostress, positioning of dislocations, etc.) properties of the die tool materials.
