Head Injury Criterion (HIC)

Dear sir,

I am doing Head Impact on ip and plotted the acceleration curves in hyper graph. But i couldnt extract the HIC value from the vehicle safety preferences tool as it is showing rectangular curves as shown in the attachment, can i know how can i get hic values from the curve perfecly in hypergraph?

Hi,

you need to load the Vehicle Safety Tools preference file in HG (File > Load > select Vehicle Safety Tools > Load)

Next, injury>HIC>Hic-Curve, chose the acceleration curve (shift+click), set windows length and finally click on apply.

Hi,

Thank you for the reply, I had chose the acceleration curve, but when i clicked on apply, the acceleration curve which had been filtered by SAE 1000 soon became a flat line which with a Y value of , and the HIC curve appeared as a rectangle, just like the pic that Ramakiran posted. Is that a normal result? Thanks a lot !
