Preliminary Static Balancing of Rotating Masses Using MS Excel Solver

Chavdar Pashinski

Abstract: The balancing of rotating elements is an important condition for reducing the reactions that arose in their supports thus ensuring stable and long-term operation of the construction. In the case of massive composite rotating structures, it is prudent to pre-arrange the individual components before their welding or assembling in order to achieve maximum static balancing. This could facilitate the subsequent final bench balancing. The purpose of this study is to demonstrate how MS Excel Solver can be applied to achieve preliminary static balancing of rotating masses, specifically for arranging the blades of a Francis turbine runner, to minimize eccentricity.
