Abstract: A tuned mass damper for reducing vibration on a component includes a shaft connector member configured to be coupled to the component and a cable termination member. The tuned mass damper also includes at least one cable coupled to the shaft connector member and to the cable termination member such that vibration of the component is transferred to the at least one cable via the shaft connector member and increased or decreased by the at least one cable.

Abstract: A gas turbine engine turbine section has tie rod assemblies interconnecting an inner diameter structure and an outer casing. Each tie rod has: an inner diameter end; an outer diameter end; and an eyelet of an outer diameter spherical bearing formed at the outer diameter end. A first clevis carries a spherical ball of the bearing, a shank of said clevis extending to an outer diameter (OD) end. A tensioning bolt is mated to a threaded opening in said clevis OD end whereby tightening said bolt applies a tension to said rod. A radial span between a center of the outer diameter spherical bearing and an inner diameter surface of the outer casing is at least 50% greater than that between an outer diameter (OD) surface of the outer ring and the center.
