    摘要: An apparatus and technique for determining the abrasion potential for tire treads is presented. A tire is rotatably and forcefully brought into contacting engagement with a reflective surface received upon an illuminated glass plate. A charge coupled device monitors the internal reflection light which evidences a grey level corresponding to the force of engagement between the associated portion of the tire and the glass support plate. A marker is placed upon the tire centrally within a region of interest. The video image of the marker and region of interest is analyzed as to slip and force at that area. The product of the slip and force functions is an indication of frictional work at the interface between the tire and support surface and is correspondingly an indication of the propensity of the tire to wear.

    摘要: A friction testing machine and method for measuring friction characteristics between a test sample and a friction surface. The machine and method are particularly suited for measuring the coefficient of friction between a rubber specimen or a tread element and different friction surfaces at different sliding velocities, contact pressures and orientations. The machine includes a carriage, a friction surface, a motion device, a sample holder, a variable weight loading device, and a force measurement device. The motion device to cause relative movement between the carriage and the friction surface in forward and reverse directions and the sample holder holds a sample in frictional engagement with the friction surface during this forward and reverse movement. The variable weight loading device loads the sample holder so that a selected load can be applied to the sample in a direction normal to the friction surface. The force measurement device obtains a measurement indicative of the frictional force resisting movement of the sample as it is moved in the forward and reverse directions. The processor controls the motion device, controls the variable weight loading device and/or records the measurements obtained by the force measurement device.

    摘要: An apparatus and related methods for capturing a digital foot print image of a tire and for extrapolating load-deflection curves of the tire is presented. A frame carries a test pod that is coupled to a tire to perform various tests. In one application, a loading plate couples the tire to a transparent plate on the test pod where a camera captures a digital gray-scale image of the tire foot print. A processor converts the gray-scale image into a pressure map wherein each pixel of the digital image is correlated to a pressure value. In another application, the loading plate couples the tire to a sliding cover plate on the test pod, wherein the loading plate is incremented through a plurality of load values at predetermined inflation pressures. By using two inflation pressures, the processor extrapolates further load-deflection curves for the tire at other inflation pressures. The apparatus also provides a unique way for imparting camber on the tire during the above tests. The data collected from the foot print image and load-deflection curves may be used to analyze the construction, operation, noise generation characteristics and performance of the tire.

    摘要: A method and apparatus for generating various tire profiles. A linear-linear-rotary table carries a non-contacting probe that sequentially scans the entire outer surface of a tire. The non-contacting probe collects measurement data which is transferred to a processor to generate an average cross-sectional tire profile or a high definition cross-sectional tire profile of the tire being measured. The processor, in conjunction with the non-contacting probe, provides an automatic ranging feature which eliminates the need to manually adjust the non-contacting probe prior to the collection of measurement data.
