The drawing to the right highlights three features on the
uplock which were considered for reinforcement.
Feature A -- Main Boss and Hole
for the locking rod bearing.
Feature B --
Horizontal torque box for stiffening the side wall.
Feature C -- Bolt
studs on the access wall.
The casting engineer should consider which
features are subject to high stresses and do a stress analysis to determine if the feature
should be reinforced and filleted to meet the load safety factors.
