摘　　要：采用软件I-deas建立液压锥阀三维模型并对网格进行划分,运用CFD方法对液压锥阀进行解析,得到阀芯颈部直径对液压锥阀阀芯作用力的影响规律。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变化对阀芯作用力及稳态液动力的影响很小。A three-dimensional model of the hydraulic poppet valve was established by using software I-deas.The simulation of the poppet valve was studied by using the computational fluid dynamics(CFD)method.The regularity of the cone neck diameter on the cone resistance and steady flow force of the hydraulic poppet valve was 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 cone resistance and steady flow force.
