Abstract

Squat rack je sprava koja se nalazi u teretanama i koristi se prvenstveno za jačanje donjeg dijela tijela. Omogućuje korisnicima sigurno korištenje sprave, ali i izvođenje vježbi uz minimalan rizik od ozljeda.
Cilj ovog završnog rada je analizirati krutost squat rack-a pomoću metode konačnih elemenata i utvrditi mjesta najvećih pomaka i naprezanja prilikom djelovanja maksimalnog dopuštenog opterećenja na squat rack. U prvom dijelu objašnjena je povijest i razvoj squat rack-a te njegov značaj u treningu. Nakon toga slijedi pregled teorijske osnove konačnih elemenata i opis korištenih elemenata te opis postupka modeliranja i analize konstrukcije. U završnom dijelu rada prikazani su rezultati analize te slijedi zaključak na temelju dobivenih rezultata. Geometrijski model je izrađen uz pomoć programskog paketa SolidWorks 2020, dok je za numeričke simulacije korišten programski paket Abaqus 2023.

Abstract (english)

A squat rack is a piece of equipment commonly found in gyms, primarily used for strengthening the lower body. It allows athletes to perform exercises safely while minimizing the risk of injury.
The objective of this thesis is to analyse the stiffness of a squat rack using the finite element method and determine the locations of the maximum allowable load applied to the squat rack. The first part of the thesis provides an overview of the history and development of squat racks and their significance in training. This is followed by a review of theoretical foundations of finite elements and a description of the elements used, as well as an explanation of the modelling and analysis methodology of the structure. In the final section, the results of the analysis are presented, followed by conclusions based on the obtained data. The 3D model was created using SolidWorks 2020, while numerical simulations were conducted using the Abaqus 2023 software package.
