SINCAP MDB - 20
D. BARRIER PHOTOGRAPHIC TARGETS, TAPE, AND WELDING ROD ALIGNMENT
Tape shall be placed on the barrier face as shown in Figure 6. Place 25 mm (1 inch)
wide yellow/black checkerboard tape along the top and front of the honeycomb barrier
face centerline and along the top and front of the left edge of the honeycomb barrier face,
to align with the vertical impact reference line of the test vehicle. Two [102 mm diameter
(4”)] targets will be placed on top of the barrier face 400 mm from the barrier centerline.
Additionally, the CG marker and other known location markers shall be visible and
labeled on the MDB in the overhead view, and photographic targets [102 mm diameter
(4”)] shall be placed on the MDB at the rear cross member accelerometer location on the
left side of the frame.
A welding rod sharpened to a point on one end will be attached along the left side vertical
surface of the honeycomb barrier in the horizontal plane level with the mid-door of the
test vehicle as shown in Figure 6 and Figure 7. Also, see note regarding impact point
height, Section 9.4B. The sharpened tip of the welding rod shall be positioned and
attached with duct tape so as to contact the test vehicle body sheet metal during pre-test
setup when the MDB is positioned against the side of the test vehicle. The tip should be
located in the center of the target described in Section 9.4B. During the impact event,
the point of the welding rod will provide a permanent indication on the test vehicle impact
line. For redundancy, the initial contact between the tip of the welding rod and test
vehicle shall be recorded by Camera No. 3.
