To accommodate the small specimens, the commercial testing machines used for the study required modifications in terms of spans and distance between loading head
In each group, there are two specimens subject to axial load applied by a flat loading head
(SJ1) and a stiffened one (SJ2), respectively (Table 1).
One linear variable differential transducer (LVDT) was attached in horizontal positioned to the loading head
to monitor the deformation occur and connected to the data logger to received and recorded the reading during testing.
Figure 1 presents the aspect of testing rig: 1--the test spherical roller bearing; 2--the testing head; 3 termoresistance lubricant temperature measurement sunk in the oil bath; 4--electromagnetic transducer for cage speed determination that receives the pulses from the magnets 5; the elastic element 6 measures the thrust outer load on the axial ball bearing 7; 8 and 10 are two elastic bodies (low thickness); 9 and 11 are resistive transducers submitted to traction, bending respectively, by the rotation tendency of the loading head
, due to the friction torque in the roller bearing; 12 and 13 represent the gravitational system for radial outer load.
Failure was typically caused in tension at mid-span by rupture near a knot or under the loading head
, in the lower diameter side of the specimen.
The Odyssey simplifies the pick and place system by moving the container into the correct position beneath the loading head
while the product is being picked up.
movement rate was 0.6 mm/minute (0.024 inches/minute).
For flexure tests, the machine was equipped with an extended base made from a steel double I-beam 20.5 feet long and a steel loading head
7 feet long.
Traders at Pirwadhai cattle market said they were off loading heads
at even below break-even rates.
For high volume applications, IPL Robot's vision control system can operate up to six loading heads
and, if required, each head can be programmed to produce a different pack format.
The loading heads
were equipped with a load evener, and both reaction-bearing plates were able to pivot.
The machine has a large component sequencer with two in-line loading heads
. It features an automatic tray stacker, while keeping a maximum board size of 460 X 440 mm.
