| 摘要： | A vehicle's vertical dynamic wheel force acting at the tire-road interface is a significant factor in causing pavement damage. Work that involved configuring a two-axle, 66,750-N (15,000-lbf) truck for dynamic wheel force measurement is described. Strain gauges were installed in a shear strain measurement mode on the axle housing of the vehicle. Inertia compensation was included when calculating tire-road forces. A 12.7-mm (0.5-in.) step and a 2-Hz sinusoid with a 12.7-mm (0.5-in.) peak-to-peak amplitude were used as inputs to a hydraulic vehicle shaker. The measured vehicle response data were in good agreement with those predicted by computer simulation. |
