    摘要: A method for correcting offsets in sensors includes mounting, on a rotating machine, a first set of sensors in locations selected to measure vector loads in a first set of coordinates. The method further includes mounting, on the rotating machine, a second set of sensors in locations selected to measure vector loads in a second set of coordinates, wherein the first set of coordinates and the second set of coordinates rotate with respect to one another when the rotating machine is operating. The method also includes utilizing measurements from either or both of the two sets of sensors to correct offset errors in vector loads measured by the other set of sensors.

    摘要: A method for balancing a rotor of a rotary machine, wherein the rotor includes at least two rotor blades and a rotor shaft, includes receiving at least one measurement of either a load, an acceleration, or a displacement that pertains to at least one bending moment acting on the rotor shaft, determining at least one value of the at least one bending moment acting on the rotor shaft based, at least in part, on the received at least one measurement, and determining a pitch offset angle value of at least one rotor blade that facilitates reducing the at least one bending moment acting on the rotor shaft.
