The Effect of Inflation Pressure on Tire Force and Moment Characteristics

Event: KSAE Spring Conference
In this study, the selection guide of tire inflation pressures are proposed to improve ride and handling quality. At the steady running stats, the standard of the inflation pressure is determined to fit the ride, handling and stability, wear, and fuel consumption performance etc. Based on the tire cornering theory, the effect of inflation pressure on tire force and moment characteristics affecting on vehicle handling maneuver was compared experimental results to theoretical analysis. The items for tire testing were the spring rate, footprint, and force and moment test. ADAMS code, which has been widely applied to the vehicle dynamics, has been used to simulate the vehicle/tire maneuver according to the inflation pressure. It is very helpful for the drivers to improve the ride and handling by controlling tire inflation pressure properly, and for the chassis/tire engineers to optimize the design factors related to inflation pressure.
