METHOD FOR SUPPRESSING RESONANCE OF VEHICLE-MOUNTED FAN AND SYSTEM

WIPO Patent Application WO/2021/068732

A1

A method for suppressing the resonance of a vehicle-mounted fan, and a system. The method comprises: according to the difference between the actual vibration value and a preset vibration value of a fan, determining whether resonance is generated between the fan and a locomotive body; and if resonance is generated between the fan and the locomotive body, then adjusting the output frequency of the fan so as to eliminate the resonance between the fan and the locomotive body. On the basis of the establishment of a matching relationship between parameters such as locomotive speed, fan speed, vibration frequency of an outer drum of a fan, and the temperature of a cooled component, a fan resonance trend is determined according to the difference between the actual vibration value and the preset vibration value of a fan; and by actively adjusting the output frequency of the fan, for example, by periodically adjusting the output frequency of the fan, the technical effect of eliminating resonance between the fan and a locomotive body is achieved.
