Inner Rib Band without damping material
For the validation of the rib module of the WorldSID many different tests have been performed. One single rib consists of two rib bands - an inner and an outer band. On the inner side of the inner band a blue damping material is tied. All ribs are built in a similar way. The difference in the shoulder, thorax and abdomen ribs are in the geometry and in the thickness of the damping material. The rib module is shown in the figure below:

Figure 20: Thorax construction of WorldSID
The inner rib bands of the shoulder and the third thorax rib are tested without the damping material. Here, a pendulum test is performed with two different velocities on the single rib band as depicted below.

The pendulum mass is 1.9 kg and a high and a low velocity are used. As results, the rib deflection (IR-Track), pendulum accelerations and the movement of the rib clamp from a video evaluation in global x- and y-direction are used.
The results of the tests are shown in the following pictures.
