Abstract.   In this project, a synthesis of nonlinear elastic characteristics is processed into a one-sided bonded chain system with a final number of degrees of independency, for given periodic disturbances with a whole-number values of circular frequencies of inducement and at given sinphase of harmonious oscillation of mass system Using Chebishevliev's polynomials, in a project exact analytical expressions are extracted for nonlinear elastic characteristics in a system that is being observed.
The exactness of extracted analytical expressions for nonlinear elastic characteristics is confirmed by results derived from solving a specific example.

SINTEZA NELINEARNIH ELASTIČNIH KARAKTERISTIKA U SISTEMU SA VIŠE STEPENI SLOBODE PRI SINFAZNOM HARMONIJSKOM OSCILOVANJU
U ovom radu se obradjuje sinteza nelinearnih elastičnih karakteristika u jednostrano-vezanom lančanom sistemu sa konačnim brojem stepeni slobode za zadate periodične poremećaje sa celobrojnim vrednostima kružnih frekvencija pobude i pri zadatom sinfaznom harmonijskom oscilovanju masa sistema. Korišćenjem Čebiševljevih polinoma, u radu se izvede tačni analitički izrazi za nelinearne elastične karakteristike u posmatranom sistemu. Tačnost izvedenih analitičkih izraza za nelinearne karakteristike potvrdjuje se rezultatima dobijenim rešavanjem konkretnog primera.
