Evaluating wear of a tire with a non-axisymmetric tread pattern

A computer-implemented method for evaluating wear of a tire with a non-axisymmetric tread pattern, the method comprising:

• providing a wear model of the tire configured to convert a frictional energy rate into a wear energy rate;
• providing a first three-dimensional (3D) model of the tire with the non-axisymmetric tread pattern;
• generating a plurality of simplified 3D models based at least in part on the first 3D model of the tire with the non-axisymmetric tread pattern;
• performing a plurality of steady-state transport analyses based at least in part on each one of the plurality of simplified 3D models;
• post-processing the results of each of the plurality of performed steady-state transport analyses;
• and
• evaluating the wear of the tire with the non-axisymmetric tread pattern based on the post-processed results of the plurality of performed steady-state transport analyses and the wear model.

A computer program product comprising a non-transitory computer readable medium having instructions stored thereon, wherein the instructions are executable by a computer to cause the computer to carry out operations for evaluating wear of a tire with a non-axisymmetric tread pattern, the operations comprising:

• providing a wear model of the tire configured to convert a frictional energy rate into a wear energy rate;
• providing a first three-dimensional, 3D, model of the tire with the non-axisymmetric tread pattern;
• generating a plurality of simplified 3D models based at least in part on the first 3D model of the tire with the non-axisymmetric tread pattern;
• performing a steady-state transport analysis based at least in part on each one of the plurality of simplified 3D models;
• post-processing the results of each of the plurality of performed steady-state transport analyses;
• and
• evaluating the wear of the tire with the non-axisymmetric tread pattern based on the post-processed results of the plurality of performed steady-state transport analyses and the wear model.
