In general, the number of planes required for the modal trial mass set is one more than the number of modes which must not be affected. In addition, the Unified Balancing Approach is not restricted to planar modes. In this chapter, the theoretical deve

This chapter begins with a theoretical discussion of the principle of reciprocity and its application to flexible rotor balancing. The particular means by which reciprocity can be applied to improve the influence coefficient and Unified

Influence Coefficient Balancing,iminate, or minimize, the synchronous rotor response due to unbalance. The analytical development and implementation procedures for influence balancing are presented in this chapter. A method for identifying and eliminating non-independent balancing planes is also presented.

Review of Literature on Rotor Balancing,to the rotor balancing literature did not appear until about 1930. Prior to the 1950s, the balancing literature was concerned with the balancing of rigid rotors and, in a few cases, very simple flexible ones. There is no documentation during this period of any systematic balancing procedure using mo

Rotor Balancing Methods and Instrumentation,r or not rotor flexibility is taken into account. That is, flexible rotor balancing procedures take into account rotor flexibility, while rigid rotor balancing procedures do not. Many flexible rotor balancing methods are suitable for balancing rigid rotors. However, rigid rotor balancing methods are

Modal Balancing,eloped, but are largely intuitive in nature. They seek to balance the rotor, one mode at a time, with a set of masses specifically selected not to disturb previously balanced, lower modes. This chapter includes the analytical background and typical procedures for modal balancing.
