Solution:
A three dimensional finite element model (FEM) was built of the
locking mechanism in question to provide analysis support. The
FEM was used to determine how the component behaved under design
loads and whether or not a postulated undesirable rotation would
occur for one of the parts. The FEM demonstrated the desirable
behavior of the safety mechanism. Further, it predicted that the
component was adequately designed per industry standards. Calculated stresses were
compared to code limits and found to be acceptable. Based upon
these findings, the parts were manufactured and tested
successfully.
This analysis satisfied the equipment buyer’s concern. After the
design evaluation and successful testing of the safety
mechanism, the equipment manufacturing activities continued on
schedule.
