Crash Analysis (HIC)
Use this dialog box to calculate the Head Injury Criterion (HIC) values.
Settings
| Time channel | Specifies the data channel containing the time values of the signal in seconds. The values of the data channel must be monotonic increasing. |
| Acceleration | Specifies the data channel containing the acceleration values of the signal in gn (acceleration of gravity). |
| HIC value | Specifies whether DIAdem calculates the HIC value. |
| HIC 36 value | Specifies whether DIAdem calculates the 36 ms value. |
| HIC 15 value | Specifies whether DIAdem calculates the 15 ms value. |
| HIC XY value | Specifies whether DIAdem calculates the HIC value with adjustable window width. |
| HIC(d) value | Specifies whether DIAdem calculates the HIC(d) value. |
| Window width | Specifies the width of the window for calculating the HIC value in milliseconds. |
 | Note The HICVersion variable receives the algorithm version number, which is independent of the DIAdem version number. |
 | Refer to the description of the HIC criterion for further information such as mathematical background, input values, and directives and laws. |
 | If you want to use waveform channels in this dialog box, follow Rule 2.2 for Calculating with Waveform Channels. |
Result
The calculation results are in the 4*5 variable matrix HICRes and the channel properties of the input channel. The HIC values are specified in gn (acceleration of gravity) and the time values in ms:

| Result~HICUser~WindowWidth | Receives the width of the window for calculating the HIC value in milliseconds. |
 | To calculate quantity-based in DIAdem, click the Calculate Quantity-Based button on the DIAdem ANALYSIS toolbar. When executing quantity-based calculations, DIAdem checks whether the program can also execute calculations on physical quantities in the same calculation. If DIAdem cannot execute the calculation because the physical quantities are unsuitable, the program displays an error message. Refer to the Help page Calculating Quantity-Based and Non-Quantity-Based in DIAdem for the conditions and rules for quantity-based calculations. |
