We have been busy working on numerous projects over the last couple of months.
Finite element analysis work on components seems to be very popular, we will be blogging a few small examples:
JNDC were contracted to perform an FEA analysis on the sheave assemblies to establish yield stress under a static load of 14,400lbs. (64,054N)
The analysis was carried out in two stages, the first was a quarter model testing the wheel with bearings and the second part was the aluminium structure.
Fine mesh was used to control the areas of high interst as shown:
The study results showed high stresses at the interface of the cable and wheel. Also the high stress showed the interface of the bearing with the fixtures as expected.
