Ooooooof.

 

I used the winch on the jeep and a hilift jack to fix a boo boo on the rear bumper on the work truck. No pix tho.

 

For me?!

 

For the underride device? That's the white thing that I was talking about welding beams on

Essentially when cars crash with the side of a tractor trailer or other large commercial vehicles, then they can get pinned and dragged under until everything stops moving. Additional, because the collision point is higher in those types of crashes, the cars crumple zone is not absorbing impact and in turn directing tbay crash energy into the passenger cabin. Rear underride protections on trailers are mandated in the US (also called the mansfield bar) but there are no side underride regulations. The goal here was to design a side underride system before side underride regulations are required in the next few years.

So that picture is a top down view of a 1/4 scale underride model in a scaled energy collision in a T-bone style collision. The wooden block in the center represents the front of a car and is loosely based size-wise on a Corolla front crash bar. The black thing is the frame rail representation and used for fixturing it to the crash tester. This test was equivalent to Toyota Corolla T-bone at 35mph.
