Abstract

Abstract: The threepoint method is a relatively practical dynamic balancing method for fans. In this method, an identical trial mass will be located in proper sequence on three positions,the angles between two of them are all 120°,for measuring the three vibration values, then the drawing diagram by using the CAD software. The result of the threepoint method can get perfect effect in the site conditions, the calculation and the diagram are accurate, and the vibration amplitude will be reduced less than 0.05mm by using this method.

Key words: three-point method for dynamic balancing, trial mass, balance point, application
