| description | A method and system for increasing damping capacity in cast metal parts by utilizing dry friction between individual wires of a sheathed rope is disclosed. The rope is embedded into the part during casting. Sheathing the ropes in a thin layer of the same metal as the casting prevents molten metal from infiltrating individual wires during casting, thus allowing inter-wire friction during the part vibration. There are two ways to distribute the ropes within a part during casting. The first way is to distribute the ropes uniformly across an entire part whereby damping capacity of the metal part increases uniformly as well. The second way of distributing the ropes is to spatially distribute them according to a pattern to increase the damping capacity only in the part regions that have the highest vibration amplitudes or stress during system vibration. Both methods of distribution may be combined in a single part. |
