摘　　要：为建立准确的新型液态金属磁流体发电机等效电路,分析端部效应对发电机性能的影响,从该类发电机的基本稳态电磁关系出发,在发电通道内部三维数值分析的基础上,建立考虑端部效应的等效电路模型,并给出该等效电路模型中各参数的计算公式。利用该等效电路模型,对实验样机的稳态输出特性进行计算,并和不考虑端部效应的等效电路模型的计算结果、实验结果进行对比分析。样机的计算结果和实验结果对比表明,给出的等效电路模型和计算方法是正确的,具有较高的计算精度。In order to build an accurate equivalent circuit model ot LMMHD（Llquid Metal Magneto Hydro Dynamlc generator and analyze the end effect on its performance,an equivalent circuit model is built based on its basic steady-state electromagnetic characteristics and the 3D simulations for its MHD channel. Formulas are given for calculating the model parameters. The steady-state output performance of a prototype generator is calculated with the proposed model and the calculative and experimental results are compared between models with and without end effect,which shows that,the proposed equivalent circuit model and calculation methods are valid with higher computational accuracy.
