Combined Bending and Torsion Apparatus- Engineering Lab Training Systems.
Technical Description
This test unit enables various
equivalent stress hypotheses from materials science to be checked
experimentally. Specimens made of different metals can be placed in a
state of stress in several axes. A circular shaped load plate is used as
a lever for the load moment, loading is applied by attaching weights to
the circumference of the plate. The specimen is clamped in the centre
of the plate using clamping levers. Via the defined points for the
application of force, combined bending and torsion loading is generated.
The angular position of the load weight can be moved in 15° steps. The
deformation is measured diametrically opposite the points where the
force is applied, that is at the point of maximum deflection. In this
way the measurement error due to the deformation under load of the test
apparatus is minimised. Compensation for the dead weight of the plate
and compensation for the load weight ensure specimen loading is free of
transverse forces.
