  • Abstract:
    The Wheel Force Transducer was developed for the Federal Highway Administration under Contract DOT-FH-11-9437 for dynamic measurement of vertical, longitudinal and transverse truck wheel loads. Modification No. Two (2) to the development contract required that a limited static calibration and a functional dynamic test of the transducer be completed prior to delivery. The tests involved three setups: 1) The transducer was statically loaded to 3000 lb for transverse calibration in a shop setup. 2) The shear gages were calibrated under static loads up to 8000 lb with the transducer mounted on a loaded truck. 3) For the functional dynamic test, the transducer outputs were monitored on a strip chart recorder with the truck in motion over short distances. Figure 1 includes a photo of the transducer mounted on the test truck. It should be recognized that these calibration tests were limited in several respects: The available static loads did not approach the full-scale sensor capacity. The method of loading and force measurement allowed only limited evaluation of crosstalk effects. The functional dynamic test involved only low speed. operation over a smooth surface.
