| Abstract: | A numerical simulation method based on the flow dynamic model is introduced to study the dynamic characteristic of the small hydraulic bumpers. The results of numerical simulation under different work conditions are coincided with the experimental data well. The relationship between kinetic parameters and the maximum capability of absorbed energy is investigated. The numerical simulation could be applied to instruct the type-selecting and optimum design of hydraulic bumpers. |
