Abstract
A subjective assessment of ride quality was undertaken in order to estimate the relationships among 22 factors that affect concepts of ride quality and to assess the interaction of these factors with 7 ride quality issues. Nine line-haul drivers drove and rated each of 16 tractor-trailer vehicles. The factors, driver vibration, ease of steering, and interior cab noise determined overall impressions of ride quality. Of the issues, front axle load, tractor configuration, tractor rear suspension, trailer suspension, trailer load, wheel base length, and newer and older cab designs, the latter evoked the clearest differentiation of ride quality between paired vehicles.
