    • Influence of the thickness of a nanolayer composite coating on values of residual stress and the nature of coating wear 

      Vereschaka, A.; Volosova, M.; Chigarev, A. V.; Sitnikov, N.; Ashmarin, A.; Sotova, C.; Bublikov, J.; Lytkin, D. (MDPI AG, 2020)
      The article discusses the influence of the thickness of the wear-resistant layer of the Zr-ZrN-(Zr,Al,Si)N nanolayer composite coating on the values of residual stress and the nature of coating wear. The study focused on coatings with wear-resistant layer thicknesses of 2.0, 4.3, 5.9, and 8.5 Zm, deposited using filtered cathodic vacuum arc deposition (FCVAD) technology. The X-ray ...

    • Inspection robots with piezo actuators: modeling, simulation and prototypes 

      Becker, F.; Zimmermann, R.; Minchenya, V.; Lysenko, V.; Chigarev, A. V. (БНТУ, 2011)
      Models, simulations and experimental setups of resonant inspection robots are presented. The goal is to show ways to cope with the new requirements and to use the given chances to create novel mobile robots. For the creation of a directed motion the vibration behavior of simple beams and plates is used. It is possible to design robots for 2-dimesnional locomotion which are ...

    • Ray expansion in inhomogeneous and stochastic media 

      Chigarev, A. V.; Chigarev, Ju. V. (БНТУ, 2018)
      Simulation of wave propagation processes in inhomogeneous media is based on kinematic and dynamic principles for the process of ray propagation and wave surfaces (fronts) in different media. Huygens' principle of constructing wave fronts in according to algorithm of a contact transformation is easily implemented if the perturbation region is non-concave.
