定长冲跑控制阀稳压过程仿真研究

Research on pressure stabilization process of constant runout control valve

基于Fluent软件对液压阻拦系统的核心部件——定长冲跑控制阀进行仿真研究。建立基于动网格的内部流道的三维模型,利用Fluent软件对阀芯运动的内部流道三维模型进行数值模拟。采用弹簧光顺和局部网格重构方法结合Profile运动边界驱动机制实现网格区域运动,计算稳压阶段的进口压强,为定长冲跑控制阀设计提供依据。

Considering the constant runout control valve （CROV） is the heart of the hydraulic arresting gear system,a three-dimensional model of flow field calculation which is proposed based on dynamic mesh.Numerical simulation of flow field in a spool motion is carried out by Fluent software.A spring-based smoothing method and local remeshing method combined with Profile driven mechanism is applied in mesh zone movement.The pressure of the inlet is calculated.The result can give theoretical support for the design of CROV.
