PERHITUNGAN DIAMETER MINIMUM DAN MAKSIMUM POROS MOBIL LISTRIK TARSIUS X3 BERDASARKAN ANALISA TEGANGAN GESER DAN FAKTOR KEAMANAN

Keywords: Shaft, Safety factor, Guest’s Theory

Abstract

The development of the automotive industry in Indonesia that uses electrical energy is still of a competition in the students. One of the electric car is named Tarsius X3 belonging to University of Bangka Belitung that has 2 kilowatts of power and a shaft as rear wheel drive system.  The rear wheel drive system will be used to transfer power to the wheel. Based on the result of tensile test, material of shaft is ductile that has 622,46 N/mm2 yield strength dan 649,21 N/mm2 tensile strength. Shaft is overhanging beam that has the diameter of suppoting beam is 25,3 h6 mm. Shaft is loaded by torsion and 12-16 shock load. The purpose of this research is to get minimum and maximum the diameter of supporting shaft based on shock load using maximum shear stress theory or Guest’s theory that is calculated manually. The result of calculation, the minimum diameter of shaft is 21,66 mm, the shear stress maksimum is 51,87 N/mm2 and the safety factor is 12. And the maximum of diameter of shaft is 23,84 mm, the shear stress mimimum is 38,90 N/mm2 and the safety factor is 16.
