Neck Pendulum Test
The neck calibration test is simulated as described in the WorldSID manual ISO-15830 part 2. The test setup is depicted in the figure below. The neck is adapted to a long pendulum. The pendulum runs into a part of honeycomb to get decelerated, thereby causing the neck to bend against the load direction. As mass replacement, the head form is used instead of the original head.
Neck pendulum calibration test setup
In the test, the load cell forces and moments are measured and the rotations of the points A and B are used to describe the kinematics of the neck.
The results and the corresponding calibration corridors are shown in the following figures.
