| Abstract: | The internal leakage of hydraulic dampers is modeled with prearranged fluid layer on the basis of structural characteristic of dampers,then,the fluid grid model of dampers with high accuracy is established,and used for CFD simulation.Finally,the low speed characteristics and internal fluid field distribution of dampers are obtained.The experiments prove that the CFD simulation is satisfactory accurate. |
