ABSTRACT

This chapter analyzes a uniform beam, a tapered beam (which can be considered as a good model of a helicopter rotor blade) and a beam with general polynomial variation in mass and stiffness (which can be considered as a good model of a wind turbine rotor blade). It provides results from numerical studies on Clamped-Free Rotating Beams (CFRBs), hereinafter referred to as clamped free rotating beam. Instead, a non-rotating beam with torsional and translational springs at the free end was presented as the isospectral counterpart. Discrete models of a family of isospectral non-rotating beams can be constructed with different values. As in the case of uniform CFRBs, the range of values that guarantee practically realistic discrete models, is narrow.
