摘　　要：为掌握各因素对交流电力测功机转矩的影响程度,测得机器的转矩、转速、馈网电流、馈网电压、馈网频率和效率;基于模糊聚类理论和灰色关联理论,建立了模糊灰色关联分析模型,并对众影响因素进行分析。结果表明,各因素对转矩的影响程度不一,转速、馈网电流、馈网电压、馈网频率、效率对转矩的模糊灰色关联度分别为0.31076、0.96521、0.41341、0.62299、0.87962,即馈网电流is对转矩T的影响最大,其次是效率η、馈网频率fs、馈网电压us,对转矩的影响最小的是转速n。In order to hold the influence factors which effect on the torque of alternating current electrodynamometer, the torque, rotation speed, feeding networks current, feeding networks voltage, feeding networks frequency and efficiency is measured. By using fuzzy cluster theory and grey relation theory the fuzzy grey relation analysis model is established to analyze these factors. The result shows that the influence of rotation speed, feeding networks current, feeding networks voltage, feeding networks frequency and efficiency on the torque is 0.31076, 0.96521, 0.41341, 0.62299 and 0.87962, respectively. The maximum influence on the torque T is feeding networks current is, next is efficiency q, feeding networks frequencyfs and feeding networks voltage us, respectively. The minimum influence on the torque T is rotation speed n.
