Seatbelt Fitting

Purpose:

This interface can be used to create seatbelts and fit them to dummy models. The seatbelt fitting algorithm uses segment sets for defining the contact surface between the seatbelt and the dummy. This provides a more flexible way of defining which element faces should be included in the contact search for the seatbelt/dummy interaction while position the belt. One or several segments sets can be seleted for defining the contact surface on the dummy. If no segment sets exists in the dummy, they can easily be created using the Set Data .

Function:

Simple : Create simple belt (*ELEMENT_SEATBELT only).

Mixed : Create mixed belt (Shell elements with *ELEMENT_SEATBELT at the ends).

Mixed

  • Belt Width : Width of the belt.

  • Elem/Width : Number of elements across the width of the belt.

  • N1->Shell: Distance from first picked node to where shell elements begin.

  • Nlast->Shell : Distance from last picked node to where shell elements begin.

  • 1D Part ID : Part ID for the *ELEMENT_SEATBELTs.

  • 2D Part ID: Part ID for the *ELEMENT_SHELLs.
