Desain dan Analisis Velg Mobil Berbasis Aluminium Alloy

Abstract

Wheels on the car is the frame of a wheel that holds the style and stress as a result of the weight of the vehicle and the impact or blows from the road surface. The blow from the road surface can result in voltage and deformation on wheels. Aluminum alloy wheels have a region called the critical area is located in the hub, spoke, and flange. One of the strengths wheels in receiving stress is affected by the number of spokes. To overcome these problems required an analysis of the number of spokes in the wheels of the car. This study was to analyze the influence of the number of spokes 10, 12, 14 and the number of spokes 10, 12, 14 with the addition of the thickness of the flange area of 3 mm on a car wheel. Wheels modeled using AutoCAD and simulated using ANSYS 14.0 Workbench software based on Finite Element Method ( FEM ) for comparison with the standard wheels and look for the best design. In this study, results found that the number of spoke alloy wheels 10 with the addition of the area of the flange thickness of 3 mm is the most excellent design and optimal compared with other designs. The maximum stress that occurs at 52.148 MPa and maximum deformation occurs at 0.5393 mm
