摘　　要：母线配置对于铝电解槽的电磁场与MHD(磁流体动力学)稳定性有着非常大的影响,在设计新的较大电流强度的铝电解槽时尤其重要,本研究通过运用商业软件ANSYS并结合自定义程序,对于各种不同母线配置参数下的500kA铝电解槽物理场进行了大量的仿真模拟,重点研究了母线的配置参数如立柱进电比,立柱连接的阴极棒数,大面阴极母线垂直位置,端头母线垂直位置,列槽间距,邻槽数目以及槽底补偿电流配比等,同时结合自定义的稳定性评估函数展开了计算分析与讨论。Busbar configuration is most important to the electromagnetic fields and MHD（Magnetohydrodynamics）stabilities in the aluminium electrolysis cell, especially for the newly designed cell of higher amperage; Various busbar configurations are built and modeled by the custom code based on the commercial package ANSYS for the 500kA aluminium electrolysis cell. Configuration parameters such as side riser entry ratio, number of cathode bars connected to each riser, vertical location of side cathode bus and short side cathode bus, distance between rows of cells in potline, the number of neighboring cells, current percentage of compensation busbar carried passing under cell etc. along with large MHI） computation based on the custom evaluation tunetion are simulated and discussed.
