Involving the measurement of internal forces and mechanical stresses on the measured circular or ring cross section with strain gage

摘要

The involvement of the measurement of the internal forces and the stress at the measuring ring or the ring cross section is cha a typical in that for each measuring channel is connected only radial strain gauge (2) deformation such that at the measuring ring or the ring cross section (1) is optimally deployed seven radial strain gauge (2) deformation. Their location is such that the angular spacing of 120 ø to the normal direction placed two radial strain gauges (2) deformation and further angular spacing of 120 ø is placed strain gauge to 90-degree rose (3) consisting of three radial strain gauges (2) deformations . The angle of 90 ø from strain gauge 90-degree rose (3) is located couples (4) radial strain gauges (2) deformation diverted from the normal angle of 45 ø. Strain gauge 90-stage rose (3) is disposed on top of the measuring ring or the ring cross section (1) in the direction of action of tangential forces.
