Three-Dimensional Tire Deformation on Deformable Surfaces
ABSTRACTAsystem was devised to measure three-dimensional deformation of a pneumatic tractor tire at three positions across the tread width on both lug and undertread surfaces. Tire deformations were compared to measured radial and tangential stresses at the soil-tire contact surface. Results showed that maximum normal stress occurred at an angular position on the tire ahead of maximum radial deformation. Maximum tangential stress occurred at a tire angular position before maximum tangential deformation.
