INFLUENCE OF TRIAL WEIGHT ON SINGLE-PLANE ROTOR BALANCING USING AMPLITUDE ONLY

Abstract

This paper introduces the research results on the influence of the trial weight
in single-plane rotor balancing, where only the results of measuring the vibration
amplitude of the device are used. In other words, there is no need to determine
the phase during the balancing process. In the first section, the theory of single-
plane rotor balancing using amplitude only will be summarized. This method is
also known as the four-test run method or the three-point method. In the next
section, an experimental balancing device is used to evaluate the influence of the
trial weight on the results during the balancing process using the above method.
The results and discussions on the influence of the trial weight will be presented
and then applied to balance industrial equipment. The research results show that
a reasonable calculation and selection of the trial weight will bring efficiency and
safety in the process of handling unbalanced equipment.
