    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 !
