block is facing away from the pendulum. The lumbar mounts directly to the
small end of the central block. In the lumbar spine test no load cell or load
cell structural replacement is required between the lumbar spine and the
head form. (See
Figure 23
right and
Figure 24
right.)
Two rotational potentiometers are used to measure the angle of the head form
relative to the pendulum arm. One potentiometer is attached to the pendulum
interface, the other to the head form (see
Figure 23
and
Figure 24
). A thin rod
connects the potentiometers. The rod should be fixed to the head form
potentiometer (using an M3 set screw), but be able to slide freely through the hub
on the axis of the pendulum interface potentiometer. The rod must be protruding
from both potentiometer axes equal length. A balance mass is attached to the
opposite side of the head form to assure symmetrical loading of the neck and
lumbar spine. The potentiometer and balance mass are mounted on the sides of
the head form with their common centerline perpendicular to the movement of
the pendulum. This can be seen in
Figure 23
and
Figure 24
.
The neck and lumbar spine test fixture can be used for both frontal and lateral
testing of the head and lumbar spine. For testing in frontal direction the head
form discs are parallel to the axis of the pendulum, see
Figure 23
. For lateral testing
the head form center line is perpendicular to the axis of the pendulum, see
Figure
24
. Both configurations use three screws for fixing the discs to the central block
and the positions (frontal and lateral) of the angle transducer. The angle
transducer and the balance weight of the head form must be repositioned when
changing from frontal to lateral testing and vice versa.
Full Body Pendulum
The full body pendulum, part number 033-9920 “Q6 Probe Assembly” (see
Figure
25
), consists of a hollow metal tube closed at both ends, two axles with suspension
pulleys and a speed vane. An accelerometer which measures the longitudinal
acceleration must be mounted on the rear end. An Endevco model 2262CA-200
or equivalent is recommended.
