Nieliniowe drgania elastycznie posadowionych silników tłokowych z cylindrami w układzie V

The paper deals with vibrations of elastically mounted V-type engines with reciprocating and rotating unweighted masses. The non-ideal power source and variable rotating speed of engine are taken into account. The behaviour of analysed systems is described by non-linear differential equations which are solved by means of the asymptotic method of Krylov-Bogolubov-Mitropolsky.
