Analisis Simulasi Struktur Chassis Mobil Mesin USU Berbahan Besi Struktur Terhadap Beban Statik dengan Menggunakan Perangkat Lunak Ansys 14.5

Abstract

Chassis designing needs to be analized by finite element simulation to get the strength of chassis on Mesin USU car actually the driver is in it. The purpose is how to getting the simulation’s effect of chassis on Mesin USU I car and on Mesin USU II car when both are applied loading which using Ansys 14.5 software. The research was carried out in several stages of working: the chassis modeling by software SolidWorks Premium 2011 and finite element simulation using ANSYS 14.5 software. After doing the simulation with 700 N load on chassis Mesin USU I acquired 0,96 mm maximum deflection, 0,6415 mm ground clearence deflection, 22,563 MPa maximum stress, 11,65e-5 mm/mm maximum strain. And 700 N load on chassis Mesin USU II acquired 3,29 mm maximum deflection, 2,236 mm ground clearence deflection, 53,217 MPa maximum stress, 26,71e-5 mm/mm maximum strain. With 25 kN load on chassis Mesin USU I acquired 31,542 mm maximum deflection, 21,682 mm ground clearence deflection, 741,59 MPa maximum stress, 371,12e -5 mm/mm maximum strain. And 3,8 kN load on chassis Mesin USU II acquired 17,074 mm maximum deflection, 11,582 mm ground clearence deflection, 277,64 MPa maximum stress, 139,39e -5 mm/mm maximum strain. The conclusion of this study is the effect of chassis loading can be determined through the simulations with Ansys software during the geometry modeling is correct
