FIELD: physics; measurement. ^ SUBSTANCE: present invention pertains to force-measuring technology. The load measuring device, working on three mutually perpendicular axes, and moments about these axes, comprises four elastic elements, fixed to a base at corners of a square, made in form of separate bars with a cannular cross-section, on which tensoresistors are put, a rigid force transmission plate and a base, joined by elastic elements. All tensoresistors are put on elastic elements along their formations. For each measured load, two tensoresistors are put on each elastic element. Tensoresistors are put on diametrically opposite sides of the elastic element. The centres of the tensoresistors for measuring loads, lying in the plane of the force transmission plate on all four elastic elements lie in the same plane, parallel to the plane of the force transmission plates. The centres of tensoresistors for measuring loads, perpendicular to the plane of the force transmission plate, as well, lie in the same plane, parallel to the plane of the force transmission plate. ^ EFFECT: increased accuracy and wider range of load measurements. ^ 4 dwg |
