This article presents an innovative algorithm and mathematical model of a torsional vibration viscous damper. The problem of torsional vibrations damping in a multicylinder internal combustion engine is extremely important for the reliable operation of a drive unit. The effective reduction of the vibration amplitude extends the service life and prevents failures that generate logistic and transport problems. One of the key parameters used to assess the quality of vibration damper operation is the temperature. This criterion is so important that it is the main indicator for the possible replacement of dampers installed in trucks, locomotives, and ships. Despite the importance of this parameter, the literature lacks mathematical models that describe the thermodynamics of damper operation. Therefore, the authors of this paper developed and presented an innovative thermohydrodynamic model of a torsional vibrations viscous damper, which was used to determine the operating parameters.
