摘　　要：为探究汽车空调用电磁离合器皮带轮上减重槽的加工位置、切槽深度和宽度对电磁离合器产生电磁吸力大小的影响,建立了该离合器的有限元优化计算模型,在忽略了影响计算精度的部分不规则结构后,根据单一变量原则,借助有限元软件ANSYS电磁分析模块,计算得到了该电磁离合器在各单一因素影响下的电磁吸力变化规律,给出了皮带轮减重槽的加工位置和尺寸的优先选取值.结果表明:为了在实际加工时能较多地切除材料并保证精度,在仅考量电磁吸力而不考虑结构刚度等因素的情况下,该电磁离合器皮带轮的减重槽可以偏向皮带轮内测加工,减重槽切槽宽度可选择为6 mm,切槽深度可选择为7 mm.To explore the electromagnetic suction variation regularities respectively caused by the change of processing position, cutting depth and width of the pulley multi-pocket of a kind of automotive air-conditioning electromagnetic clutch, based on the preliminary calculation and analysis, the finite element optimization calculation model was estab- lished after ignoring the irregular structure which influenced the grid division and influenced the calculation precision. According to the principle of single variable, after the finite element electromagnetic analysis for the model with the help of the software ANSYS, these variation regularities had been gotten, and the priority selection values of the pro- cessing position and structure size of the electromagnetic clutch pulley multi-pocket were recommended. Results showed that the only consideration factors such as electromagnetic suction without considering the structural stiffness, and in the actual process could more removal of material and to ensure accuracy, the position of multi-pocket of elec- tromagnetic clutch pulley could be close to the inner, the cutting width could be accepted as 6 mm, the cutting depth could be accepted as 7 mm.
