在集成块内部孔道连通时，为避免各流道之间发生干涉及减小压力损失，必须合理安排流道尺寸。鉴于出油口直径、工艺孔长度、工艺孔直径以及直角转弯长度等将对液压集成块的流道特性产生重要影响，运用ANSYS／Fluent模块对集成块内部三维孔道进行仿真和数值计算，通过仿真模拟得到了速度流线云图，并比较了不同出油口直径、工艺孔长度、工艺孔直径以及直角转弯长度对流道压力产生的影响，分析了造成压力损失的原因，得到了使流道压力损失最小的流道尺寸配比。研究成果为水下控制模块封装系统底盘上液压集成块通油孔优化提供了理论支持。

When internal channels of the hydraulic manifold block are connected, flow channel size must be reasonably arranged to avoid interference between flow channels and reduction of pressure loss?Considering signifi?cant influences of inlet and outlet diameter, auxiliary hole length and diameter and quarter turn length on properties of hydraulic manifold block flow channels, simulation and numerical calculation are conducted for 3D flow channels in the hydraulic manifold block by using ANSYS/Fluent module, a speed line nephogram is obtained by simula?tion, comparison is made for influences of oil outlet diameter, auxiliary hole length and diameter and quarter turn length on flow channel pressure, the analysis focuses on the cause for pressure loss, and a flow channel size ratio is finally obtained to provide theoretical supports for optimization of oil holes of hydraulic manifold block on packa?ging system chassis of underwater control module.
