Bishop (1) proposes an effective way of balancing a flexible rotating shaft using one motorized balancing head. To determine the optimal location of the head and the amount of correction unbalance required, the change in modal properties due to the presence of the balancing head has to be completely examined, which is often laborious and time consuming. In this paper, a simple and effective method to determine the optimal location of the balancing head and the amount of correction unbalance, adopting a structural dynamics modification (SDM) approach, is presented and an example problem is solved. It is shown that the current approach yields results almost as accurate as those obtained by finite element analysis, while computational time and effort are remarkably reduced.
