摘要
针对液压技术中广泛应用的插装型锥阀,建立三维模型。对锥阀阀芯开启和关闭的运动过程,应用CFD分析软件Fluent进行了仿真计算和可视化研究,给出了锥阀阀腔内的速度场、压力场分布。对比分析表明CFD动态仿真,可更准确地反映液压锥阀内部的流场情况。
Aimed at the widely use of the poppet valve in the hydraulic technology, the 3-D model is estblished, using the FLUENT computational fluid dynamics （CFD） software package.The flow field of opening and closing are simulated. Moreover the pressure distribution,velocity distribution are obtained through calculation. By the contrast, we find that the CFD dynamic simulation can be used clearly to study the complex flow inside the popper valve.
