摘要

提出一种旋转配流激振阀，为研究进口压力和阀芯换向频率对旋转配流激振阀输出特性的影响规律，采用多参考系方法（Multiple Reference Frame Model，MRF）进行流场动态仿真，获得旋转配流激振阀输出压力和流量的动态特性曲线，并搭建电液激振实验台对仿真结果进行验证。研究结果表明：进口压力由14MPa增至16MPa，旋转配流激振阀输出压力、流量峰值分别提高了1.16%和6.98%；阀芯换向频率由100Hz增至180Hz，输出压力、流量峰值分别降低了1.24%和18.6%；进口压力工况下，输出压力、流量的仿真和实验结果的平均误差分别为0.18%、2.14%；换向频率工况下，输出压力、流量的仿真和实验结果的平均误差分别为0.10%、1.76%。仿真和实验结果整体趋势基本一致，证实了旋转配流激振阀结构的合理性及仿真模型的正确性。

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.
