Isolation of Flaws by Use of Thermal Differentials on a Tire Under Mild Loading Conditions.

摘要

An experiment was conducted using a Monsanto Infrared Tire Flaw Detector (TFD) to confirm the hypothesis that areas in tires having poor adhesion or separations tend to achieve a greater rate of temperature rise under conditions of moderate stress than unflawed areas. Three types of stress were tried: constant tire deflection;alteration of inflation pressure;alteration of wheel speed. Tire-to-wheel force in at least one case gave evidence of greater thermal rise rates than in other areas of the tire believed to be normal. (Author)
