Abstract.The interaction between the road surface and vehicle's tire may significantly determine the stability of a vehicle. We could study the tire contact-pressure to road surfaces through a numerical simulation in this present study. In particular, the main purpose of the study was to present an illustration of the effect of the varied loads to the tire, which would affect the contact pressure on the road surface sand stress distribution on the tire by employing a commercial ABAQUS software, based on the finite element method. To make the process of data analysis easier, the tire was assumed to be made from natural rubber which composition consisted of 2 layers of the inner tire and 1 layer of carcass. In pre-conditions, the tire was given air pressure as much as 17 psi, and loads as much as 2 KN, 6 KN, and 10 KN; then, the air pressure was increased to be 30 psi; consequently, the simulation results of stress distribution and deformation on each of loads condition would be acquired. The simulation results indicated that the loads carried by the tire on the vehicle were an important factor to determine the tire-stress profile.
Abstract. The interaction between road surface and tire on a vehicle may strongly determine the vehicle's stability. This study was conducted to find out the stress distribution as a result of pressure on the tires rolling across the speed bumps. This study used Abaqus software to simulate the movement of the tire, which rolls across the speed bump to determine the stress distribution that may occur. The tire component material used was a full path rubber on a speed bump. For the boundary conditions of the study, it was assumed that the tires had load variations as much as 2 kN, 6 kN, 10 kN, as well as pressure variations as much as 17 Psi, 30 Psi, 40 Psi. The tires were then rolled 8 km/h crossing the speed bump. Modeling speed bumps also varied i.e. the first variation of speed bumps that have a height of 50 mm with a width of 250 mm, the second variation of height 75 mm with a width of 300 mm, and a third variation of height 100 mm with a width of 400 mm. The simulation was done by giving the tire pressures as much as 17 Psi, 30 Psi, 40 Psi and loads as much as 2 kN, 6 kN, 10 kN. Further, the tires were rolled three times. It was rolled crossing the first speed bump, the second, and the third, respectively. Results showed stress distribution's fig and graphs. From the analysis results and simulation, it was shown that the greater the load received by the tires, the higher stress they produced.
