ABS Pumping 성능 특성에 대한 연구

In the process of developing HCU (Hydraulic Control Unit) of MANDO ESP (Electrical Stability Program) System, several designs of pump are suggested. There are many ways to improve the performance of a pump, nevertheless, several parameters are considered to optimize the performance in this study: spring constant, and shape of Spring Support. In order to analyze performance of pump in each case, two-dimensional CFD analysis is conducted. The main interest in this study is in change of pressure inside the piston assembly and outlet valve assembly during the Pumping operation.
