Abstract:
Tire is one component of the suspension system and has beneficial effects on reducing vibrations caused to the vehicle. This study aims to determine the factors affecting the damping and stiffness of the tire is carried out. The modeling of factors were identified. For testing the modeling effort is to be made to the instruments used to measure the damping and stiffness of the tires. To make the structural static analysis, dynamic and modal was to have sufficient structural strength and the displacements and stresses are sensibly placed. Factors that have influence on the hardness of the ring diameter, the outer diameter of the tire, tire pressure, tire tread depth, tire wall thickness, width of the tire, and also the name of the first movement on hard tires do not work. It can be said with barely 0.7 percent decrease per cent reduction in diameter. By increasing the diameter of the ring (inner diameter of the tire), damping and stiffness increases slightly with the increase of the internal diameter of the damping and stiffness of about 0.54 to about 0.48 percent increase
