- Automatic connections with all beam and surface elements
- Named selection on a B-pillar node in contact with the impact object
- Nodal Displacement and Nodal Rotation to lock the named selection in space
- Fixed support on the back face of the impact object
- Displacement, locking the chassis from moving along the X axis
- Acceleration of 49m/s^2 away from the collision object
Regulation Standard Result (1 inch square chromoly tubing with 0.065" thickness):
Observations
- Here we can see that the most stress (516.8MPa) is in the top corner of the B pillar panel that is in contact with the catamaran
- Having 1 inch square chromoly tubing with 0.065" thickness performs much better than 1.25" circular chromoly tubing with 0.049" thickness
- Seems to pass regulations
Upper B-pillar Impact Results (1 inch square chromoly tubing with 0.065" thickness):
Observations:
- The B-pillar will most likely fail and break
- Extremely dangerous, vehicles with higher bumpers (i.e. pickup trucks) will have a higher impact like this
