8.2 Certification of the Neck

General

The neck test is a component test, which is performed using a pendulum as defined in
CFR49 part 572. To certify the Q3 neck, remove it from the dummy. The complete neck
consists of the following parts:

The neck is attached upside down to this pendulum. A head form is used to load the neck.
This  head  form  consists  of  two  flat  disks  connected  by  an  interface,  which  allows
certification of both the neck and the lumbar spine. The head form rotation during the
test is measured using two rotational potentiometers. One is installed on the base of the
neck-pendulum  interface  the  second  one  is  attached  to  the  head  form.  Both
potentiometers are linked with a thin shaft (see Figure 29 and 30).  The sum of the two
angles measured on the potentiometers is the angle of the head relative to the pendulum.
Moment is measured using an upper neck load cell IF-217 mounted between the head
form and the neck.

The data acquisition system and all instrumentation must comply with the requirements
of  SAE  J211.  All  data  channels  should  be  filtered  using  a  hardware  filter  prior  to  A/D
conversion according to SAE J211.

The pendulum acceleration should be measured with an accelerometer, which is located
on the pendulum arm, 1657.4 mm from the pendulum pivot in accordance with the CFR
49 Part 572.
