摘  要：
A brief description of a newly developed rubber-oil-hose WIM system was presented. The WIM system was portable and much cheaper than equivalents. By analyzing its measuring principle and characteristics, a simplified weighing model has been derived. Using nonlinear least square optimization algorithm, useful parameters of static axial load could be extracted and estimated. Meanwhile, velocity of the weighed road vehicle could be measured and calculated precisely by utilizing the correlation between the first and the last hose signals. The results of series of tests showed that the algorithm is feasible and the WIM system could satisfy some accuracy. Therefore, it provided an effective and economical means of overload check and regulation enforcement in China.
