Title: HEAVY VEHICLE SUSPENSION VARIATIONS AFFECTING ROAD LIFE --TRUCK DESIGNERS SPRUNG? SYMPOSIUM ON HEAVY VEHICLE SUSPENSION CHARACTERISITCS, PROCEEDINGS, CANBERRA, AUSTRALIA, MARCH 23-25, 1987
Abstract: The Canadian weights and dimensions study has examined practical vehicle parameter variations with regard to their contribution to vehicle stability and control and road life. This paper presents one facet of the study that concentrated on an experimental study of the effects of suspension parameter variations on dynamic wheel loads. A prime mover and semi trailer were modified to form a representative test vehicle for the study. All load carrying axles were instrumented to provide continuous road loading data. Two prime mover tandem drive suspensions and three semi trailer tandem axle suspensions were studied. Variations in axle load, axle spacing and suspension pitch attitude were examined. Input variables included road roughness, speed and discrete bumps associated with grade level railway crossings and bridge approach irregularities. The influence of dynamic axle loads on flexible pavement deformation was also studied. The findings of this research will be presented in a manner so as to show the range of performance characteristics of the suspensions and will discuss suspension parameter variations with respect to improving road distress (a). For the abstract of the covering record of the symposium, see IRRD no 808884.
