DYT103 - Introduction to Airbag Analysis and Occupant Safety using Dytran

Horizontal spacer

In this course we will discuss the steps to perform an Occupant Safety Analysis. Some of the topics to be covered are: discussion on the input cards needed, modeling of an airbag, self contact, inflator, holes, permeability and heat losses. Patran will be used to position a Dummy, define contact between Dummy and airbag and contact between Dummy and seat belt. Several workshops are used to illustrate these techniques, followed by discussion of the results for a more thorough understanding of the problems analyzed.
