  • TITLE: THE TRANSFER PHENOMENON OF ENERGY IN MECHANICAL SYSTEMS OF VIBRATION DAMPING
  • AUTHOR(S): I. Nochnichenko, O. Yakhno, D. Kostiuk, V. Kryvosheiev
  • ABSTRACT: The article is devoted to the analysis of transfer processes from the point of view of the energy balance in the damping system. It is shown that damping systems are based on the physical process of converting mechanical energy into thermal energy, with subsequent dissipation into the environment. The full distribution of energy in damping problems takes the following form: the mechanical energy of movement is absorbed due to the hydraulic resistance of the fluid and is transformed into a dissipative component, which can reach up to 80% of the total energy in the system. The dependence of the total power loss of the shock absorber in variable operating conditions and the scheme of physical processes and energy transformations in damping problems, which are in dissipative processes, are given. The article provides principles that can be used to design devices and modules of a wide class of damper systems with the possibility of energy recovery and storage due to the introduction of a damper system, for example, a motor-generator, an induction coil, and other energy storage systems

MULTI-CHANNEL MEASURING INSTRUMENT AND DESIGN OF A ROLLING BEARINGS TEST RIG

  • TITLE: MULTI-CHANNEL MEASURING INSTRUMENT AND DESIGN OF A ROLLING BEARINGS TEST RIG
  • AUTHOR(S): B. Savic, U. Pesovic, M. Popovic, M. Nikolic
  • ABSTRACT: This paper presents the vibrodiagnostic test rig for analyzing the condition of rolling bearings. The rollingbearings are the most widespread mechanical elements, which are also considered critical elements within the mechanical assembly. Typically functionality, reliability and exploitative properties of the entire machine system depend on the functional capabilities of rollingbearings. The paper presents a design of a rolling bearings vibrodiagnostic test rig, which allows for simulating loads that are close to real loads during the operation of bearings, as well as a measuring instrument VibroLog, which is used for the acquisition and display of measured data. The newly developed measuring instrument VibroLog modular device for measuring and analysis of several diagnostic bearing parameters: vibration, speed, temperature and sound pressure. With this modularity, it enables easier diagnostics and speeds up the process of finding problems and faults in bearings.

FROM HAND MACHINE TO INTELLIGENT MOBILE MACHINE – ROBOT

  • TITLE: FROM HAND MACHINE TO INTELLIGENT MOBILE MACHINE – ROBOT
  • AUTHOR(S): Y. Kuznietsov, O. Shevchenko, A. Gutnik
  • ABSTRACT: The analysis of the evolution of technical systems, which include machine tools, shows the significant impact of industrial revolutions on the change in the structural and functional features of new generations of technology. Using the convergence of knowledge and an interdisciplinary approach, it is possible to carry out long-term genetic prediction during the transition from manually controlled machines to intelligent mobile robots, on which the processing of products is carried out while moving from the loading position of the workpiece to the unloading position of the finished product.
