摘要

This paper aims at comparing the strength of Al-Al2O3-SiC composite and structural steel through simulation as a material for automobile chassis application in electric vehicles. This work consists of the simulation done on a body-in-frame chassis of a four-wheeler vehicle using Ansys Workbench. The chassis has been designed on SolidWorks and Siemens NX. Various researchers in the past have performed several tests on the Al-Al2O3-SiC composites pertaining to structural, mechanical, and thermal properties like SEM, XRD, tensile and compressive strength, thermal conductivity, wear resistance, corrosion resistance, etc. The Al-Al2O3-SiC composite used in this work was prepared through stir casting process. Stir casting was chosen among several available techniques due to its simplicity and less cost. Many researchers in the past have prepared high-quality composites with stir casting technique. The properties pertaining to the strength and density of the Al-Al2O3-SiC composite and structural steel, namely, yield tensile strength, yield compressive strength, bulk modulus, shear modulus, and Poisson’s ratio were used in the simulation setup as the input properties for simulating the chassis under static loading condition. The static load that the chassis was subjected to was kept fixed at 60,000 N. The results of the simulation revealed that Al-Al2O3-SiC composite exhibited better engineering and true tensile strength as compared to structural steel. From the results of the simulation under static loading condition, it may be inferred that Al-Al2O3-SiC composite will perform better in the automobile chassis as compared to structural steel.
