Abstract: Systems and methods for damping torsional oscillations of downhole systems are described. The systems include a downhole drilling system disposed at an end of the downhole system in operative connection with a drill bit. A damping system is installed on the downhole drilling system, the damping system having at least one damper element configured to dampen at least one HFTO mode. At least one mode-shape tuning element is arranged on the drilling system. The at least one mode-shape tuning element is configured and positioned on the drilling system to modify at least one of a shape of the HFTO mode, a frequency of the HFTO mode, an excitability of the HFTO mode, and a damping efficiency of the at least one damper element.

Abstract: A second inner member and a second insulator are provided in a second ring-shaped member forming a torque rod. A first bore section and a second bore section are provided in front of and in the rear of the second inner member. The insulator has an elastic arm section extending in the direction of a Y axis. A spring adjustment recess extends in a slit shape in the direction of an X axis from an end of the first bore section. The spring adjustment recess forms an unrestricted part of the elastic arm section by the second ring-shaped member, whereby the Z spring in the axial direction of the inner member is lowered, and the XZ spring ratio can be changed greatly while maintaining the size of the X spring in the main vibration inputting direction.

Abstract: A torsion spring may be formed as a bar spring or helical spring comprising a spring wire of fiber composite material. In some examples, the torsion spring comprises a number of layers of fiber reinforcement, which are impregnated with a matrix material. The layers may comprise tensile-loaded fibers and compression-loaded fibers. Groups of layers of the same loading direction may exist and, seen from an inside to an outside, the group stiffness of at least two groups may differ. Likewise, methods for making such torsion springs of fiber composite material are disclosed.

Abstract: A torsion bar is provided that is easy, quick, and cost effective to manufacture. The torsion bar may extend along an axis and have a first end and a second end that is spaced from the first end. The torsion bar may have an active section positioned between the first and second ends. The active section may also have a length defined along the axis. A cross-section transverse to the axis may define a contour of the torsion bar where the contour may be uniform along the length of the active section. The contour may define at least one of a polygon and a polygon-like shape.
