| 摘 要： | 建立了液压锥阀的几何模型和数学模型，利用Fluent软件的动网格技术对其内部运动流场进行了数值模拟，并对模拟结果进行了分析。由分析结果可知：随着锥阀开度的减小，人口速度逐渐降低，流量相应减少，入口及阀芯凹角处涡旋区长度逐渐减小直至涡旋区消失。

| Abstract: | Based on the physical numerical modeling of the hydraulic poppet valve,the inside movement field was simulated by numerical method with the dynamic gridding technology of Fluent.The analysis results indicate that the intake rate and flux are reduced with the minishing of the poppet.The eddy section's length of the intake and the concave corner of the valve core is gradually minished and disappeared at last. |
