Title: Vibration damping method and apparatus

Abstract

The present invention provides vibration damping method and apparatus that can damp vibration in more than one direction without requiring disassembly, that can accommodate varying tool dimensions without requiring re-tuning, and that does not interfere with tool tip operations and cooling. The present invention provides active dampening by generating bending moments internal to a structure such as a boring bar to dampen vibration thereof.

Apparatus and method of preloading vibration-damping bellows

Patent Cutburth, Ronald W [Tracy, CA]

An improved vibration damping bellows mount or interconnection is disclosed. In one aspect, the bellows is compressively prestressed along its length to offset vacuum-generated tensile loads and thereby improve vibration damping characteristics.

System and method for damping vibration in a drill string using a magnetorheological damper

Patent Wassell, Mark Ellsworth; Burgess, Daniel E.; Barbely, Jason R.; ...

A system for damping vibration in a drill string can include a magnetorheological fluid valve assembly having a supply of a magnetorheological fluid. A remanent magnetic field is induced in the valve during operation that can be used to provide the magnetic field for operating the valve so as to eliminate the need to energize the coils except temporarily when changing the amount of damping required. The current to be supplied to the coil for inducing a desired magnetic field in the valve is determined based on the limiting hysteresis curve of the valve and the history of the magnetizationmore » « less

System and method for damping vibration in a drill string

Patent Wassell, Mark Ellsworth [Kingwood, TX]; Turner, William Evans [Durham, CT]; Burgess, Daniel E [Middletown, CT]; ...

A system for damping vibration in a drill string can include a valve assembly having a supply of a fluid, a first member, and a second member capable of moving in relation to first member in response to vibration of the drill bit. The first and second members define a first and a second chamber for holding the fluid. Fluid can flow between the first and second chambers in response to the movement of the second member in relation to the first member. The valve assembly can also include a coil or a valve for varying a resistance of themore » « less
