Abstract

A rotary flow-distribution excitation valve was proposed. In order to study the influence of inlet pressure and spool commutation frequency on the output characteristics of the rotary flow-distribution excitation valve, the MRF method was used to simulate the flow field dynamics and the dynamic characteristic curves of the output pressure and flow rate were obtained. And an electro-hydraulic excitation test bench was built to verify the simulation results. The results show that: when the inlet pressure increases from 14MPa to 16MPa, the peak output pressure and flow rate of the rotating flow distribution excitation valve increased by 1.16% and 6.98% respectively; when the spool commutation frequency increases from 100Hz to 180Hz, the peak output pressure and flow rate reduces by 1.24% and 17.5% respectively; when the inlet pressure is the same, the average errors of the simulation and the experimental results of the output pressure and flow rate are 0.18% and 2.14% respectively; when the commutation frequency is the same, the average errors of the simulation and the experimental results of the output pressure and flow rate are 0.10% and 2.71% respectively. The overall trend of simulation and experimental results is basically consistent, which proves the rationality of the structure of the rotating distribution excitation valve and the correctness of the simulation model.
