| Popis: | Cilj ovog rada jest odrediti utjecaj elemenata dinamičke sprege na energetsku učinkovitost mehanizma mahokrila. Uz pomoć programskog paketa MSC ADAMS propisuje se funkcije gibanja krila s obzirom na kriterij postizanja traženog kinematičkog profila uzorka gibanja mahokrila. U ADAMS se ubacuje geometrija modela rađenog u SolidWorks programu na koju se zatim propisuju odgovarajuća kinematska struktura primjenom dinamike više tijela (engl. Multybody Dynamics). Dodavanjem elemenata dinamičke sprege nastoji se poboljšati energetsku učinkovitost mehanizma. Na temelju usporedbe rezultata dobivenih za dvoje različitih (s obzirom na raspon krila i frekvenciju mahanj) modela mahokrila zaključuje se kako se dodavanjem linearne, jednako kao i nelinearne opruge značajno poboljšava učinkovitost mehanizma. The goal of this thesis is to analyse the influence of dynamic coupling elements on energy efficiency of the flapping wing mechanism. The flapping wing motion, which follows the kinematic profile of a flapping wing, can be simulated using ADAMS (on two different models based on their wingspan and flapping frequency of the wings). The 3D model, which was made in SolidWorks, is set with its kinematical constraints in ADAMS using multybody dynamics. By adding dynamic coupling elements we are trying to improve the energy efficiency of the flapping wing mechanism. Based on the given results, we can determine, by using linear as well as nonlinear springs, a significant improvement in the efficiency of the mechanism. |
