Abstract

The present invention discloses a six-component balance. The balance comprises a basic platform (10); a loading platform (20) arranged in parallel with the basic platform (10) and configured to put anobject to be measured; six brace rods arranged between the basic platform (10) and the loading platform (20), wherein the two ends of the brace rods (30) are respectively hinged with the basic platform (10) and the loading platform (20), the brace rods (30) are provided with an unidirectional force sensor (31) and an active deformation compensation actuator (32), the unidirectional force sensor (31) is connected with the input end of a feedback signal processor, and the active deformation compensation actuator (32) is connected with the output end of the feedback signal processor. The six-component balance performs compensation through the active deformation compensation actuator (32) to maintain the posture of the measured object so as to effectively improve the measurement flexibility of the balance.

Description

technical field [0001] The invention relates to the technical field of mechanical parameter sensing devices, in particular to a six-component balance based on a Stewart configuration. Background technique [0002] Any generalized force in space can generally be decomposed into six components in a given coordinate system, namely the force loss components Fx, Fy and Fz along the three coordinate axes, and the moment components Mx, My and Mz around the three coordinate axes . The force acting on a certain point on the research object can always be decomposed into the above six components in a given coordinate system. The six-component balance is used to simultaneously detect and sense the six components of the force, and is widely used in robotics, biomechanics, precision assembly, engineering field testing and other fields. [0003] Most of the existing six-component balances give the six components of the force in a calibrated way through the deformation degrees of differen...
