Structure with anti-vibration device comprising mass, able to slide by friction on structure surface, having center hole for passage of fixing

摘要

The structure (1) comprises an anti-vibration device (9) comprising a mass (10) fixed to the structure so that it can slide on the structure surface by friction. The mass is drilled in its center with a hole (21) having a perimeter (22) of sufficient width to allow passage of a fixing. The hole has a space (23) between the fixing and the hole perimeter. There is a cavity (19) having a depth (29) such that pushing the fixing into the cavity does not prevent the mass from sliding by friction on the structure.
