the beams in a door model and finding the crush resistance offered by both beams for a prescribed pole intrusion test according to the FMVSS 214 for side impact analysis. [6] 2. Design of composite impact beams The intrusion beam used in the selected ford taurus car is made up if high strength steel (AISI 4340). It is 945 mm in
The door intrusion beam is located in the door shell and behind the door skin. The door intrusion beam is important because it provides occupant protection in a side-impact collision. If the intrusion beam is damaged in any way, it must be replaced. It should not be straightened. The door intrusion beam may be attached to brackets on …
On the other hand, sliding friction between the impactor and the beam was also included. A friction coefficient of 0.35 was used, which is representative for the friction between steel and wide diversity of thermoplastics ... 214 protocol for crashworthiness evaluation in side door beams.
