摘　　要：建立了液压锥阀三维模型,运用计算流体动力学(Computational Fluid Dynamics,CFD)方法对锥阀进行仿真研究,得到阀芯颈部直径对液压锥阀流量特性的规律。其结果表明:在阀口开度大小相同的情况下,液压锥阀的阀芯颈部直径数值大小不会引起流量的变化,同时流量系数基本保持不变约为0.87。A three-dimensional model of the hydraulic poppet valve is established.The simulation of the poppet valve is studied by using the computational fluid dynamics(CFD)method.The regularity of the cone neck diameter on the flow characteristics of the hydraulic poppet valve is obtained.The results show that when the opening size of the valve is the same,the value of the diameter of the valve cone neck does not cause changes in the flow rate,and the flow coefficient remains basically unchanged at about 0.87.
