Shear-type transducers compensated for effects of non-uniform bending
Abstract
Abstract A SHEAR-RESPONSIVE STRAIN GAGE TRANSDUCER, MOUNTED AT SPACED POSITIONS ALONG A LOAD-CARRYING MEMBER TO CHARACTERIZE SHEAR AND THE RELATED LOADING, BUT ALSO TENDING TO DEVELOP ERROR BECAUSE OF NON-UNIFORM BENDING OF THE LOAD-CARRYING MEMBER, IS STRUCTED FOR INHERENT MECHANICAL SUPPRESSION OF BENDING-INDUCED OUTPUTS WHICH WOULD NOT OTHERWISE BE ELECTRICALLY SELF-CANCELLABLE, IN THE CASE OF A PREFERRED WEIGHT-CHARACTERIZING SHEAR-TYPE TRANSDUCER COLLECTED AT TWO LONGITUDINALLY-SPACED POSITIONS INSIDE A HOLLOW NON-UNIFORM AXLE OF AN AIRCRAFT LANDING GEAR, THE COLLECTED ELASTICALLY-DEFORMABLE SENSING ELEMENT CARRYING THE STRAIN GAGES HAS AN ASYMMETRY OF PROPORTIONS AND/OR LONGITUDINAL ORIENTATION WHICH REDUCES TO INSIGNIFICANT AMOUNTS ANY SHEAR-INDUCED DISPLACEMENTS RESULTING FROM THE PARTICULAR NON-UNIFORM BENDING OF THAT NON-UNIFORM AXLE.
