Abstract: To develop better understanding of road/vehicle interaction, as it applies to the processes that lead to vehicle-generated road damage, experimental research reproducing vehicle wheel loads in a controlled environment was conducted on a four-actuator road simulator. Three instrumented vehicles were used, two two-axle trucks and one five-axle tractor-trailer. Tests on the two-axle trucks revealed limitations of conventional wheel-load instrumentation and poor level of wheel-load replication. Four-actuator road simulator tests on the five-axle tractor-trailer revealed that conventional wheel-load instrumentation on trailers can produce very accurate load measurements.

Keywords: dynamic wheel loads; road damage; road-friendly suspension systems; road simulator testing; vehicle-road interaction; wheel load instrumentation; heavy vehicles; vehicle suspensions; simulation; trucks; tractor-trailers; load measurements.
