摘要

针对航空发动机机匣凸台在电解加工中电解液流量不能充分进入加工间隙造成流速分布不均匀的问题,提出了在阴极结构上增加一个矩形挡板的新阴极结构以提高流场的均匀性.通过COMSOL软件对阴极内壁与挡板不同间隙和挡板下壁与凸台上表面不同间隙的阴极结构等两种方案进行流场仿真,结合流速云图和速度变化曲线图得出增加挡板能够使电解液流速提高,流场的均匀性增强,并且阴极内壁与挡板间隙为 6mm,挡板下壁与凸台上表面间隙为 4mm时,流场变化最为平缓.

Abstract

In order to improve the uniformity of the flow field,a new cathode structure with a rectangular baffle is proposed to improve the uniformity of the flow field by adding a rectangular baffle to the cathode structure.The flow field simulation was carried out by COMSOL software for the cathode structure with different gaps between the inner cathode wall and baffle and the cathode structure with different gaps between the lower wall of the baffle and the sur-face of the tab,and the flow velocity cloud and velocity variation graphs showed that the increase of the baffle could improve the electrolyte flow velocity and the uniformity of the flow field.The change of flow field is the most gentle.
