ON THE VIBRATIONS GENERATED BY WOODEN CHURCH BELLS

Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2011, Vol 56, Issue 3

Abstract

In Maramures County, Romania, there is Budesti Josani wooden church inscribed on the World Heritage List. The major deterioration of its 18th and 19th paintins represent a big problem in restoration program. The vibrations generated by the bells produced cracks and detachments in the paintings layer. In order to calculate the oscillations of a bell, the bell and its clapper were simulated as a double pendulum.
