Abstract

U ovom diplomskom radu koncipiran je i konstrukcijski razrađivan sustav ovjesa na visokomobilnom višenamjenskom vozilu na kotačima HMMWV. U radu su definirani osnovni zahtjevi za vozilo i ovjes, te su analizirane uobičajene konfiguracije ovjesa sličnih vozila. Nakon detaljne analize, odabrana je konfiguracija ovjesa koja zadovoljava navedene zahtjeve. Odabrana konfiguracija uključuje neovisni ovjes sprijeda i straga s dvostrukim poprečnim vodilicama, koji se preko podkonstrukcije povezuje na šasiju vozila.
Analizirana je kinematika ovjesa i dinamika vozila kroz specifične ispitne procedure izvancestovne vožnje te su određeni osnovni parametri ovjesa i vozila, kao što su širina traga, međuosovinski razmak i klirens. Na temelju provedenih analiza, izrađeno je konstrukcijsko rješenje i kontrolni proračun kritičnih komponenata.

Abstract (english)

In this thesis, a suspension system for the high-mobility multipurpose wheeled vehicle HMMWV was conceptualized and structuraly develpoed. The study defines the fundamental requirements for the vehicle and its suspension and analyzes common suspension configurations used in similar vehicles. After a detailed analysis, a suspension configuration was selected that meets the specified requirements. The chosen configuration includes independent suspension at the front and rear with double wishbones, connected to the vehicle chassis through a subframe.
The kinematics of the suspension and the dynamics of the vehicle were analyzed using specific off-road driving test procedures, and key parameters such as track width, wheelbase, and ground clearance were determined. Based on the conducted analyses, a structural solution was developed, and a verification calculation of critical components was performed.
