ABSTRACT: This report documents the results of the Friction Snubber Force Measurement System (FSFMS) special road test program that was performed during TDOP Phase II. The FSFMS was designed, built, and shop-tested during TDOP Phase I (see FRA/ORD-78/69). Descriptions of the test equipment, procedures, methods of data analysis, results, and recommendations are contained in this report. The test program was successfully completed using friction snubber transducers to obtain friction forces in over-the-road truck tests. The primary purpose of the tests was to obtain estimates of the friction coefficients associated with ASF Ride Control and Barber S-2 70-ton trucks. The report provides some preliminary analyses using the test data and recommends areas where additional information may be extracted.
