Abstract

In the development and application of highly dynamic mechanical systems, major problems can arise from usually unwanted accompanying processes, such as torsional vibrations. The internal combustion engine is a typical dynamic system with a high probability of fracture of a system part due to the effects of torsional vibrations. In engineering practice, the IC engine crankshaft fracture due to torsional vibrations is prevented by using additional devices that allow the transfer of critical vibration modes of the crankshaft out of the IC engine operating range, or devices damping the resulting twist angle amplitudes.
This paper presents a possible approach to defining parameters of torsional oscillatory systems of IC engines needed for a preliminary selection of basic parameters of various types of torsional vibration dampers, such as the elastic damper, the balance weight damper and the dual mass flywheel. The proposed physical and mathematical models and methods of defining the input parameters were compared with experimental results.
