摘　　要：采用计算流体力学(computer fluid dynamic,简称CFD)和液压系统耦合的仿真方法,完成同时包含限压阀内气穴现象以及整个液压系统的在线耦合研究。研究过程、限压阀内气穴现象以及阀的动态运动,用CFD商业软件FLUENT进行仿真计算和流场可视化研究,而系统其他部分的计算运用一维特征法,采用软件MATLAB的SIMULINK模块来实现。在线耦合仿真用两台并行运算个人计算机来实现,仿真中必要的信号文件通过TCP/IP传输。耦合仿真的计算结果充分证实了所应用耦合原理的可行性和有效性。The cavitation phenomenon at a pressure relief valve and the dynamic coupling problem of the hydraulic system were both investigated by using the computational fluid dynamics(CFD)method.The cavitations in the pressure relief valve and the dynamic movement of the valve were visually simulated by using the FLUENT software.Simulations of the other parts were carried out by a 1-dimensional characteristic method,which was realized by applying the SIMULINK toolbox of MATLAB.The coupling simulation was carried out by employing two parallel-working computers,and the signal data were communicated through TCP/IP.The simulation results show the coupling principle is feasible and effective.
