Abstract

To study the response speed of the hydraulic pressure of hydraulic brake system, a hydraulic unit was taken as an example, and the structural principle of the key components was analyzed.Then the model of the hydraulic unit was established by AMESim for simulation and analysis, and variable-controlling approach was used to figure out how the parameters of the hydraulic unit impact the response speed of the hydraulic pressure.The result shows that the pump displacement and the size of oil return port of the regulating valve impact the pressure response speed significantly.The optimal pump displacement of this hydraulic unit is 0.3ml/r, and the optimal diameter of oil return port is 1mm.
