This class presents the most important features of LS-DYNA with respect to occupant safety simulations. Insights will be 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 on modeling methods for practical application.
This course is mainly designed for beginners working in the field of occupant safety (especially dealing with side, frontal, and rear impact). We will provide an overview of state-of-the-art airbag modeling and explain 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. Attendees will be given the opportunity to apply their acquired knowledge in sample exercises.
