abstract="The purpose of this study is to use a simulation method to ascertain the effects of dynamic loading upon the accuracy of the Weigh in Motion (WIM) apparatus. The simulation was made with the ADAMS (Automatic Dynamic Analysis of Mechanical Systems) model. A four wheel truck of the type used to carry logs was modelled, with the help of its manufacturer, Oy Sisu-Auto Ab. The simulation modelled the dynamic loading produced by three different suspension types (four axle leaf spring; four axle parabolic spring; and three axle parabolic spring), at three speeds (70, 80 and 90 km/hr), and three different road evenness profiles. The results are displayed as a function of the location of the lorry on the road, and not as a function of time, as is usually the case. The results show that if the road is very smooth there is no spatial concentration of dynamic loadings. However only a very small surface irregularity will put the dynamic loadings in phase and their spatial concentrations is then very clear.<p />",
