Engineering Physics Annotation << Back Application of the Simulation Method When Selecting Vibration Dampener Parameters Imaeva E.Sh., Shkrabiy I.S. This article describes the stages of constructing a vibration protection system model and the prerequisites for selecting its key parameters. It also substantiates the factors influencing the operation of the protected equipment. The proposed method for selecting optimal vibration damper parameters based on a simplified simulation model suggests considering a single parameter: the mass of the damping element. An example of calculating a vibration protection system model using Lagrange's equations of the second kind is provided. The mathematical framework for the calculations is based on analytical mechanics methods and Mathcad software. Keywords: damping, mass of vibration dampener, simulation, vibration dampener, vibrations of mechanisms, vibration protection. DOI: 10.25791/infizik.11.2025.1514 Pp. 42-48.
