Overview

The Head Acceleration tool processes translational head CG accelerations.  All acceleration data is output in a local coordinate system per SAE J211.

Output Overview

Sensor TypeNodout
Sensor IDDefault: Node ID 1990002
Local Coordinate SystemDefault: LCS ID 1900001
Signal TypeAcceleration Time History
Filter FrequencyDefault: 1000 Hz

Calculation Methods

1. Extract local X, Y, and Z head acceleration traces from the sensor node. Default node ID can be modified in Human Body Model Settings

2. Filter each trace individually. Note: default filter frequency can be modified in Calculation Settings
