Abstract:
A repairable high-payload six-axis load sensor comprising:a table; a base; at least three two-axis force sensing units, said two-axis force sensing units each comprising: a shear-pin load transducer removably mounted between said table and said base for measuring two orthogonal reaction forces between said table and said base and a structure for minimizing unmeasured axial loading on said shear-pin load transducer by transmitting reaction forces in an unmeasured third orthogonal direction to at least one of the other of said sensing units, said reaction forces produced by an applied load, each said shear-pin load transducer producing an electrical signal proportional to said reaction forces; and, computing means for receiving said proportional electrical signals and computing three orthogonal forces and three orthogonal torques produced by said applied load corresponding to said proportional electrical signals.
