Component Finite Element Analysis Work - Sheave Assembly

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:

Sheave Assembly
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.
