摘要

为揭示高频换向阀的阀口压力特性，降低压力损失，采用格子Boltzmann方法，并结合大涡理论模拟高雷诺数下的阀口流体流动。建立基于格子-大涡理论的高频换向阀格子模型，模拟阀不同尺寸参数下的阀口特性，得出进油腔体积和最大过流面积均对阀口压力有较大的影响，且对于一定的最大过流面积，开口度对阀口压力影响最大。结果表明格子Boltzmann方法具有准确、计算效率高等优点，可以应用于液压激振系统的分析研究。

Abstract

Abstract:In order to study the pressure characteristic curve of a high frequency reversing valve and reduce pressure loss, the lattice Boltzmann method (LBM) combined with large Eddy simulation (LES) was used to simulate high-Re flow.A lattice evolution model based on LBM-LES was established for high frequency reversing valve.The valve port characteristics under different size parameters of valve were simulated.It can be concluded that the volume of oil inlet chamber and the maximum flow area have great influence on the pressure of the valve port.For a certain maximum flow area, the opening has the greatest impact on the pressure of the valve.The results show that the LBM has the advantages of accuracy and high computational efficiency and so on.Thus it can be applied to the analysis and research of complex hydraulic exciting systems.
