To meet the requirements of the frontal neck certification test:
3.
The maximum head angle (first maximum) should be between 53.5 and 66.5
degrees.
The peak moment shall be between 18.50 and 23.00 Nm.
Lateral Neck Test
Set-up
1.
Assemble the complete neck
2.
Attach the IF-217 6 AXIS LOAD CELL and TE-2650-11 SPACER FLEXION HEAD FORM
to the head form. Slide the head form over the neck and attach with 4 M5 x 12 SHCS.
3.
Attach the neck to the pendulum interface plate (4xM5). Place the (modified) 020-
2015 (TE-2650-9) intermediate plate between the neck and pendulum interface. Align
the neck and the interface, making sure that lateral axis of the head is in the direction
of movement of the pendulum arm
(se
e Figure 30). Also, make sure that the bending
direction of the neck in the certification is the same as the initial bending direction
experienced in the test the dummy is being certified for (LHS or RHS).
4.
Attach the head form-neck system to the part 572 pendulum. The impact side of the
neck should point in the direction of motion of the pendulum (see Figure 30).
5.
Install the potentiometers to the mounting interface and on the head form’s central
block. Mount the balance weight for the potentiometer on the other side of the central
block. This ensures that the inertial properties of the head are symmetrical in the
impact direction. Figure 30 indicates the proper position and orientation of the
potentiometers.
6.
Insert the rod connecting the axes of the potentiometers and tighten the screw on the
bottom-most axis to secure the rod to that potentiometer. The other end of the rod
should be able to slide freely through the upper most transducer axis. The rod must
be protruding from both sides of the transducer axes equal length.
7.
The minimum time interval to observe between tests on the neck is 30 minutes.
