Abstract

A slight asymmetry exists in Korean beslls due to decorative sculptures, carved figures and casting irregularities. In this study, the influence of the asymmetry on the bell's best frequencies and mode shapes is studied by using finite element method and modal testing. Also measurement techniques of nodal lines and damping ratios of bells with very small beat frequencies are discussed.
