Introduction to Passive Safety

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 and fitting of seatbelts to the dummy and the definition of recommended contacts between the safety systems.

 

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 sample exercises.
