Abstract

Real life experiment cost more to acquire data and information in our daily life. In the other hand, computer simulation are an advanced system that used to explore and gain new insights into outstanding and creative function. Transportation are one of the reason that the technology evolution exceed rapidly. Wheel rim has always been the key component to allow vehicle function normally on the road. For this studies, the impact simulation are based on the different number of spokes and orientation of degrees involved. The objectives of this research are to determine the energy absorbed by the wheel rim that has 4, 5 and 6 spokes. The additional studies which is impact test of wheel rim on different orientation will also be carry out to find out the energy absorbed from the impacting event. The material used for the wheel rim and striker model are fixed which is Aluminum 6061-T6 and steel for every simulation run in this studies. The mesh size involved are 5 mm, 10 mm, and 15 mm for the simulation of wheel rim. From the result analysis, it is known that the energy absorbed of wheel rim are in the range from 592 J to 993 J. The percentage difference of absorbed energy of wheel rim are 6.98 % for 4 spoke, 9.81 % for 5 spoke and 14.67 % for 6 spoke. The percentage difference for wheel rim in different orientation are 9.81 % for 0 º, 12.32 % for 18 º, 7.83 % for 36 º . Due to the surface area of contact and different orientation of impact, the values of energy absorbed are affected in the simulation. The lower the surface are of contact, the lower the energy absorbed. This studies can be used as a guideline for further research of wheel rim with different variable such as pattern of wheel rim spokes, material of wheel rim, and mass of wheel rim
