| Abstract: |
| Pump noise is the main noise source of hydraulic systems.To improve characteristics of flow distribution of axial piston pumps, a noise reduction design is proposed.At first, the mathematical model of pressure and flow characteristics are established according to the mechanism of piston pump.The simulation result has shown that piston pump achieves better comprehensive performance at φ0=4°.Then the non-dominated sorting genetic algorithmⅡ (NSGA-Ⅱ) is adopted to optimize the structure of the triangular groove.An optimal solution(θ1=16°, θ2=85°) can be extracted by analyzing Pareto-optimal.At last, a CFD model is established, and the results obtained from the mathematical model are shown to be well in accordance with the results obtained from the CFD model.The deep causes for pressure pulsation and flow ripple of piston pump can be analyzed by visualization of CFD result. |
