摘　　要：槽结构是双极板的主要结构,电解加工是槽结构的主要加工方式之一。由于杂散腐蚀等原因,电解加工槽结构存在侧壁锥度问题。采用变电压的方法,开展单槽的电解加工仿真和实验,以改善槽的侧壁锥度。以14 V为中心电压,开展线性变电压仿真和线性变电压振动电解加工实验。研究结果表明:变电压能改善槽的侧壁锥度,在10~18 V线性变电压时可加工出比较垂直的槽。Slot structure is the main structure of the bipolar plate,and one of its main processing methods is electrochemical machining.To address the taper defects of sidewall caused by stray corrosion and other factors in the electrochemical machining slot structure,the method of variable voltage is used to carry out electrochemical machining simulation and experiment of a single cell to improve the taper of the side wall of the slot.With 14 V as the center voltage,linear variable voltage simulation and electrochemical machining experiment on linear variable voltage vibration are conducted.The research results show that the variable voltage can improve the taper of the slot sidewall,and a relatively vertical slot can be processed with linearly voltage at 10-18 V.
