Focusing on the large error of partly load-bearing dynamic weighing sensor,propose a partly loadbearing dynamic weighing model based on linear segmentation and developed a four-row paratactic dynamic weighing system,based on pavement interaction model and partly load-bearing dynamic weighing model,combined with linear segmentation. Contrast experimental results verify that error of dynamic weighting system using new model,maintains within ± 2 %,when speed changes and vehicle is start-stop state. Dynamic wei...
