When　dynamic　weighing　is　carried　out,　the　vertical　undulation　of　the　anti-skid　pattern　on　the　scale　platform　can　cause　vibrations　in　the　vehicle,　affecting　weighing　accuracy.　To　address　this　issue,　a　dynamic　model　of　the　vehicle　weighing　process　was　established,　considering　the　compliance　characteristics　of　the　tires.　An　elastic　roller　contact　model　was　developed,　and　the　equivalent　road　surface　generated　by　the　anti-skid　pattern　was　used　as　the　input　excitation　for　the　dynamic　model.　The　influence　of　a　novel　symmetrical　anti-skid　pattern　on　the　accuracy　of　weighing　in　a　flatbed　scale　under　various　factors　was　analyzed.　Simulation　results　indicate　that　as　the　width　of　the　anti-skid　pattern　increases,　the　vibration　force　on　the　vehicle　increases,　leading　to　an　increase　in　weighing　error.　When　the　spacing　between　pit-type　anti-skid　patterns　is　235　mm,　the　excitation　frequency　generated　approaches　the　natural　frequency　of　the　vehicle,　causing　resonance　between　the　vehicle　and　the　scale　platform.　The　weighing　error　can　reach　a　maximum　of　0.　21%.　The　vibration　force　and　weighing　error　generated　by　triangular　pit-type　anti-skid　patterns　are　lower　than　those　of　rectangular　pits.　Additionally,　at　higher　speeds,　the　generation　of　anti-skid　patterns　results　in　larger　weighing　errors.　©　2024　Chinese　Society　for　Measurement.　All　rights　reserved.
