O przybliżonych metodach rozwiązania nieliniowych równań ruchu elastycznie posadowionych silników tłokowych

In this paper vertical vibrations and rotation speed of an one-cylinder, elastically mounted piston engine are considered. The solutions of linear motion equations, the Krylov-Bogolubov-Mitropolskij and the averaging methods as well as the Runge-Kutta method are applied. The results of calculations can be used for the estimation of the accuracy and applicability of the approximate methods presented.
