Method of measuring wear rate in rubber tires

摘要

A method of measuring wear rate in an actual rubber tire. A section of rubber is cut out of an actual tire below the surface of the tire. The cut out section is attached to the surface of a first wheel. An abrasive substance is attached to the surface of a second wheel. The two wheels are rotated for a predetermined time, in opposite directions, in contact with each other, at uneven rates resulting in some slippage between the surfaces of the two wheels. The wear rate of the rubber tire is measured based on the changes in the cut section over time, in much less time and using less resources than required by conventional wear measurement methods.

1. A method of measuring wear rate in a rubber tire comprising, cutting a section of rubber out of the tire below the surface of the tire, measuring thickness of the section before abrasion of the section, attaching the section to the surface of a first wheel having an axis, attaching an abrasive substance, which is coated or laminated onto a substrate, to the surface of a second wheel having an axis, the first wheel having a diameter 3 to 6 times the diameter of the second wheel, rotating the two wheels under a load normal to the axes of the two wheels for a predetermined time, in opposite directions, in contact with each other, at uneven velocities resulting in slippage between the surfaces of the two wheels, wear including a wear pattern in the rubber section of the tire, and abrasion of the section, measuring thickness of the section after abrasion of the section, and measuring the wear rate of the rubber section of the tire based on changes in the section over time by using the formula ΔW/T, where T=time, ΔW=p×ΔV, p=density of the section, ΔV=L×W×p×ΔH, L=length of the section, W=width of the section, ΔH=thickness of the section before abrasion−thickness of the section after abrasion.
