摘　　要：本文用近年来发展起来的有限元方法，对流体传动与控制系统中广泛使用的液压锥阀的内流场进行数值模拟，并给出锥阀流场的速度矢量图和流线图谱。这对于进一步分析阀口处的噪声和能量损失、优化设计间内流道等具有重要的实际意义。In this paper, the finite element method developed in recent years has been used to analysis flow flow field of poppet valve which is widely ed in hydraulic transmission and control systems. The velocity vector plots and streamline patterns havwe been given. It has very important significance for us to further analyze the energy loss and fluid noise at te valve port and to optimize the flow paths.
