Introduction to Passive Safety in LS-DYNA

Particularly due to the growing amount of relevant legislation and consumer tests as well as new technological developments, the field of occupant safety in vehicle technology has become more important and also gained in complexity. The goal of this seminar is to present the most important features of LS-DYNA with respect to occupant safety simulations. Moreover, insights are provided on how to deal with the various components involved, such as airbags, seatbelts, crash-test dummies and seats. During this training, particular emphasis will be laid on modeling methods for practical application.

The seminar will provide an overview of state-of-the-art airbag models and describes the fundamentals regarding the composition of an LS-DYNA occupant safety simulation, including the positioning of the dummy model and belt routing with PRIMER, the definition of recommended contacts between the safety systems and the principle set up of airbag models.

This seminar is mainly designed for beginners working in the field of occupant safety (especially dealing with side, frontal and rear impact). During the event, attendees will be given the opportunity to apply their acquired knowledge in practical exercises.
