This book was released on 1983 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The force, torque, and energy methods of measurement are all in common use and should yield the same test results. Effects of steering, traction, and non steady-state tire operations are excluded from the recommended practice because they are still in the research stage. Methods of correcting laboratory data to road conditions are being developed.

Book excerpt: This recommended practice applies to the laboratory measurement of the rolling resistance of pneumatic tires designed primarily for use on trucks and buses in normal highway service, as defined by the Tire and Rim Association, Inc. (TRA); it does not include light truck tires (designated LT). The procedure applies only to straight, free-rolling tires under steady-state operation and includes the following three basic methods: This technical report is being stabilized because the technical committee has determined that the using community is moving towards newer technology and would like to alert users that this new technology exists which may want to be considered for new design. Refer to SAE J1269 and SAE J1270 for rolling resistance measurement.

This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Basic Methods--The force, torque, and power methods of measurement are all in common use and should yield the same test results. Effects of steering, traction, surface texture, and non-steady-state tire operations are excluded from the recommended practice because they are still in the research stage. Force Method--The chief advantage of the force method is that the only parasitic losses in the measurement are tire spindle bearing losses and aerodynamic losses associated with rotation of the tire and its wheel. The main disadvantage of this method is that the spindle force measured can contain a severe error caused by load misalignment and load-spindle force interaction ("crosstalk"). Elimination or compensation of these effects is necessary. A minor disadvantage is that the loaded radius of the tire must be measured in order to convert spindle force to rolling resistance. Torque Method--The torque method has the advantage that the measurement is direct: rolling resistance is the net torque divided by the test wheel radius. The main disadvantage of the torque method is that parasitic losses contained in the measurement include rotational test wheel losses as well as tire spindle losses. Hence, the parasitic losses are larger than those of the force method and can be of the same order of magnitude as the rolling resistance itself. In addition, speed-hunting oscillations in the drive motor can introduce errors. Power Method--The advantage of the power method is that no force or torque transducer is necessary; a voltmeter and an ammeter to measure the electrical energy input to the drive system are sufficient. The chief disadvantage of the power method is that electrical losses are included in the measurement in addition to all the other parasitic losses of the system. Thus, the parasitic losses are even larger than those of the torque method. In some laboratories, special control may be needed to prevent line voltage fluctuations from creating power surge which can distort the readings.
