Loads and Vibrations Caused by Eight Commercial Vehicles with Gross Weights Exceeding 32 Tons (32.5Mg),

摘要

The effect of vehicle weight on dynamic loading and vibrations in road structures is examined for eight commercial vehicles with gross weights in the range 32to 44tons(32.5to 44.7Mg). In general there was no obvious relationship between gross vehicle weight and dynamic loading or vibrations,but this may have been obscured by the influence of other vehicle parameters. A comparison of two vehicles having similar structural characteristics showed a slight increase in these quantities with increasing weight. This was insufficient evidence for a generalization to be made. The dynamic behavior of individual suspension systems proved to have the most influence on loading and vibrations. The mechanical coupling of some double axled systems gave rise to repeated cycles of loading. Theoretical work shows that this damaging situation can be controlled by suitable suspension design.
