摘　　要：将某型空气净化器用于对箱装体内的空气进行过滤,通过振动测试分析来掌握空气净化器的振动情况。由频谱分析得出主要激励频率,并用特征频率法对空气净化器激励进行了计算。分析表明,空气净化器激励由叶轮不平衡质量离心力、电机转子不平衡质量离心力及气流激励构成,主要激励为气流激励。该结论为空气净化器的减振设计提供了可靠的依据,并为空气净化器和箱装体构成的系统进行振动分析提供了重要支持。An air filter is used to purify the air in the enclosed space of a trunk.This paper describes the vibration test and analysis of the air filter.The main vibration frequencies are obtained through the frequency spectrum analysis,and the magnitude of excitation are calculated by using the characteristic frequency method.The result shows that the centrifugal force due to the unbalanced impeller and the electromotor rotor,and the excitation of air are the source of vibration excitation,and the main excitation is from the air.The results provide a foundation for the vibration reduction design and a support to the vibration analysis of the air filter and the trunk.
