1)Edge of plastic grille to upper radiator support: XX mm. (see Figure 3)

2)Bottom edge bumper beam to hood latch support at centre: XX mm. (see Figure 4)

3)Bumper beam to rad at centre: XXX mm. (see Figure 5)

4)Contact width: n/a  

Average Bumper Cover Displacement: X mm

Average Air Gap: X mm

Repeated Barrier Impact Test Results:

*only damaged components are described

Terminology

Vi - barrier impact velocity

Vf - barrier rebound velocity

apeak - maximum acceleration experienced during the impact

DV - difference between the initial and final velocities

Ea - energy that was absorbed by vehicle's structures in the form of plastic deformation (i.e. for yielding and distorting components) and viscous losses (i.e. releasing sound energy and generating heat for frictional losses). The difference between pre-impact and post-impact kinetic energy.

Avg. Bumper Displacement - a customized measurement jig with seven adjustable rods was used to measure the pre-test position of the bumper. After each impact, the jig was aligned with an undamaged reference on the vehicle (example rear axle) and the net displacement resulting from that impact was recorded. The average of the seven measurements was noted.

Avg. Air Gap - pressure was applied to the bumper cover until it flexed sufficiently far to contact an underlying structure. The average of two or three subjective measurements was noted.
