Abstract:

A new truck tire tester was built to measure tire forces in braking and cornering under various speed, vertical load, and slip angle conditions and on different pavement surfaces. Six of the most common truck and bus tires were tested. In general, rib tires performed better than lug tires and radial tires performed better than bias-ply tires. Overall, the radial rib tire performed best, both in braking and in cornering, among the six test tires. All of the independent test variables - pavement type, vehicle speed, axle load, and slip angle - have a significant effect on tire traction. The experimental data were processed to derive 48 regression models relating peak and sliding coefficients of braking and cornering friction and critical longitudinal slip to the independent variables. A computer simulation study using the T3DRS, Phase 4 program was also conducted to investigate the effects of suspension type, tire type, roadway alignment, pavement roughness, and surface wetness on truck braking distance. The simulation results showed that trucks may require considerably larger stopping distances than passenger cars.
