torsional testing of shafts
Besides the torsional impact tests, non-impact fatigue tests were also performed on a torsional test rig with pulsating cycles. . The stress concentration effect, produced by the fillet radius between square and circular cross-sections of the axle, was emphasized. Five groups of shafts with radius between 0.5 and 3.2 .For instance, the drive shaft of a standard rear-wheel drive automobile, depicted in Figure 1, serves primarily to transmit torsion. These shafts are almost always hollow and circular in cross section, transmitting power from the transmission to the differential joint at which the rotation is diverted to the drive wheels.Figure 4: Reversed torsional fatigue failure of a splined shaft; each spline has two cracks, each at 45 degrees to the shaftIf there are two 45 degree fracture planes in a shaft whose load does not change direction, it is an indicator of torsional vibration. A shaft fracture may have both torsion and bending fatigue forces applied to it.Our Solution. Instron ® MT Series systems offer a range of capacities for torsion testing ideal for testing drive shafts. These systems offer accurate, multi-turn capability with high torsional stiffness. Adjustable horizontal test openings and lathe .
