 Abstract
In the paper we propose the analysis of the vehicle oscillations, through a mathematical model with a small number of degrees of freedom, the vehicle vibration problem being particularly important because the car without a proper suspension loses its value, even if it has a good dynamic performance, the speed of the vehicles, usually, not being limited to the engine power but to the quality of the suspension.

 Rezumat
În lucrare se propune analiza oscilaţiilor automobilelor, printr-un model matematic, cu un număr mic de grade de libertate, problema vibraţiilor autovehiculelor fiind deosebit de importantă, deoarece automobilul fără o suspensie corespunzătoare îşi pierde din valoare, chiar dacă are performante dinamice bune, viteza de deplasare a automobilelor, de obicei, nu este limitată de puterea motorului ci de calitatea suspensiei.
