In this paper it is considered that the displacement of a cantilever beam
is the superposition of the contribution of the second mode and the prescribed
harmonic base motion. The equation of motion is one weakly nonlinear and
is solved by a combination of variational and averaging method. The results
obtained here can be used in several experimental nonlinear identification
techniques.
O ODZIVU DRUGOG MODA KONZOLNE GREDE
U ovom radu proučen je doprinos drugog moda pomeranju konzolne grede
u odnosu na osnovnmo harmonijsko oscilovanje. Jednačina kretanja je slabo
nelinearna i rešena prilogom varijacionoj i metodi usrednjenja. Rezultati
ovde dobijeni bi mogli biti upotrebljeni za eksperimentalne nelinearne
identifikacione tehnike.
