ANALYSIS OF THE CHARACTERISTICS OF PSEUDO-RESONANCE AND ANTIRESONANCE

In this pager, the analytical expressions of the dynamic compliances o f both undamped and damped cantilever beams are found by the transfer function method. From these solutions, the phenomenon of ''pseudo-reso nance'' of beams is discovered and defined The characteristics of reso nance and anti-resonance are investigated in detail. The resonance fre quencies, anti-resonance frequencies and pseudo-resonance frequencies of the cantilever steel beam are also measured. The calculated results of these resonance characteristics are compared with the experimental ones.
