Abstract

U ovom radu prikazan je razvoj zatezača remena za bicikl sa stražnjom suspenzijom. Razvoj je
započet kratkim uvodom i prikazom problema kojeg je potrebno riješiti. Potom je provedena
analiza patenata i postojećih proizvoda na tržištu. Pomoću funkcijske dekompozicije i
morfološke matrice koja iz nje slijedi – generirana su tri koncepta zatezača remena za bicikl sa
stražnjom suspenzijom. Na temelju vrednovanja izabran je koncept za daljnju konstrukcijsku
razradu. Nakon konstrukcijske razrade model zatezača remena kontroliran je numeričkom
analizom metode konačnih elemenata. Također, proveden je i dinamički proračun sigurnosti
ležaja i tijela zatezača. Nad usvojenim modelom, nakon zadovoljavanja proračuna, proveden je
proces topološke optimizacije. Na koncu su izvršene konačne evaluacije novog modela pomoću
prethodno spomenutih metoda. Konačno rješenje je diskutirano i predloženi su eventualni
pravci daljnjeg razvoja zatezača remena.

Abstract (english)

The topic of this thesis is the development of belt tensioner for bicycle with rear suspension.
The development was started with a short introduction and presentation of the problem that
needs to be solved. An analysis of patents and existing products on the market was then carried
out. By means of the functional decomposition and the morphological matrix that follows from
it – three concepts of belt tensioners for bicycle with rear suspension were generated. Based on
the evaluation, a concept was chosen for further design development. After the design
development, the belt tensioner model was controlled by numerical analysis of the finite
element method. Also, a dynamic calculation of the safety of the bearing and tensioner body
was carried out. After satisfying the engineering analysis, the topological optimization process
was carried out over the adopted model. Finally, the final evaluations of the new model were
performed using the previously mentioned methods. The final solution was discussed and
possible directions for further development of the belt tensioner were proposed.
