Abstract

Large air cooling fan system is made up of many fans. The dynamic response of the fan bridge truss is very complicated when the fans are running simultaneously. Four fans and their supporting structures are selected from the fan system as analysis object. By finite element method, vibration response produced by 15 kinds of the combinations of running of fans is analyzed. Result shows that interaction of fans can´t be neglected when dynamic response of fan bridge truss is calculated. The research result in this paper can be as the reference for calculation of vibration response of fan bridge truss.
