Dynamic Load-Sharing of Longitudinal-Connected Air Suspensions of Triaxle Semitrailer

摘要: The effects of suspension parameters and driving conditions on dynamic load-sharing longitudinal-connected air suspensions a tri-axle semi-trailer are investigated in this study. A novel nonlinear model multi-axle with is formulated based fluid mechanics thermodynamics validated through test results. road surface conditions, speeds, line inside diameter connector capability the were analyzed terms criteria. Simulation results indicate that, when larger lines connectors employed, DLSC (Dynamic Load-Sharing Coefficient) optimization ratio reaches its peak value roughness medium. fluctuates complex manner as speed increases. also that if always assumed to be than diameter, influence more significant diameter. proposed approach can used for further study additional factors (such vehicle load, static absolute pressure height spring) control methods longitudinal line.
