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.

INVERSE DYNAMICS OF A TRANSLATION-ROTATION HYBRID PARALLEL ROBOT
Matrix relations for dynamics analysis of a spatial two-module hybrid parallel manipulator are established in this paper. Knowing the relative motions of two serially connected moving platforms, the inverse dynamics prob...
A SPECIAL CLASS OF DRIP MEDIA WITH HYSTERESIS
Since the interaction phenomenon for waves of arbitrary shape and amplitude is a property of the transmitting medium rather than of the particular wave profiles, Seymour and Varley named as DRIP the media that do not rem...
