The article presents the analysis of the influence of bending-torsional coupling of vibrations in the crankshaft on transverse vibrations of the engine body. In practice, there is used a simplified model, wherein transverse and torsional oscillations are analyzed independently. With the use of the model of deformable crankshaft, the authors show the influence of bending-torsional coupling on the frequency structure of transverse vibrations. The Introduction presents the problem of vibrations in combustion engines and their modelling. Further, there is presented the elastic model of the crankshaft, together with the applied assumptions and equations of motion describing vibrations in one cylinder combustion engine . Next chapter shows numerical simulation results with their initial analysis. The whole paper is summarized with conclusions about calculations and the possibility to use the results in practice.
