Episode notes
Start With Base Plate And Concentrated Masses
- Holly began analysis focusing on the base plate since loads path through it.
- She used concentrated masses for components to get baseline loads quickly.
Model Quality Determines Confidence
- FEA is sensitive to input quality: garbage in, garbage out.
- Incorrect modeling choices can falsely show success or failure.
Model Realistic Connections
- Model boundary conditions and material properties carefully and validate connectors.
- Represent bolts, hinges, and contact slop instead of assuming infinite stiffness.
