| Abstract: | Based on the beam current theory of hydrodynamics,the dynamics and kinematics status of fluids in hydrodynamic retarder are analyzed,the calculation formulas of retarder brake force and oil charge and release time are deduced.Braking dynamic simulation model is built in SIMULINK-toolbox ;based on simulation data for a 45 t heavy-duty truck,and considering retarder oil charge time,the braking simulation results under different working conditions are obtained,finally the relative conclusions were also obtained. |
| Keywords: | Hydrodynamic retarder Brake Dynamic simulation |
