Head Acceleration

   Head acceleration

Head accelerometer and local coordinate directions

The marked node is the head accelerometer node. An accelerometer is defined at this node. This prints the results in the NODOUT file in the local coordinate system shown in the figure.

Spine Accelerations

Spine acceleration

T1, T4 and T12 accelerometer nodes

The figure above depicts the points, each point has two nodes which are used as output nodes in the NODOUT file for T1, T4 and T12 accelerations. For each first node, an accelerometer with the local directions is defined, each second node is for global accelerations.

Pelvis Acceleration

Pelvis acceleration

Node to extract pelvis acceleration

In the figure above, a plate cut through the pelvis along the z-x-plane is shown. The pelvis accelerometer is located at the back of the sacrum block. The results of the node 10005 are printed in the NODOUT file in the local coordinate system which is shown in the figure. Node 10142 is for global accelerations.

Rib Accelerations

The WorldSID 50th model is equipped with twelve rib accelerometers. On each single rib, one accelerometer is mounted on the impact side and one on the opposite side.

The nodal results are printed in the NODOUT file in the local coordinate systems of the accelerometers. On the impact side (left hand side for the left handed driver model) the nodes are:
