New Achievements in Manufacturing of Church Bells

Résumé

Analysis, modelling and design of the bells are a topical issue for manufacturers of bells, in general, and for church bells manufacturers in particular. The transition from manual design of a bell to that achieved with the computer led to  fabrication of bells capable to produce sounds of bells controlled close to those of musical instruments. It is mentioned a number of specialized software such as AUTODESK, for sizing profile of a bell; RESHAPE for analyzing and adjusting tones and WAVANAL for processing issued sound. The performances of a bell are closely related to the material used, casting technologies, possibly heat treatment and their grinding, processes that can be controlled automatically by computer.
