摘　　要：对车用空调直流无刷风机样机进行整机的振动测试和频谱分析,确定了影响风机振动的2个主要因素,即风机转子质量不平衡和无刷直流电机的换相脉动、齿槽脉动;分析了其影响规律,提出了相应的减振措施,并给出改进后的测试结果.The vibration of brushless DC fan for the air conditioner of vehicles was wholly tested,and the frequency spectrum of brushless DC fan was analyzed.The two most important factors affecting the vibration of fan,such as the mass imbalance of rotor,commutation torque ripple and cogging torque for BLDC,were determined.According to influence patterns,the corresponding damping methods were proposed,and the test results were given finally.

关 键 词：无刷直流风机 振动测试 频谱分析 减振
