Intro Safety

Within the context of automotive technology, the field of occupant safety has become very broad, which is particularly due to the growing amount of relevant legislation and consumer tests. This seminar sets out to present the most important features included in LS-DYNA in relation to occupant safety simulations while also providing insights into how to deal with the various components involved, such as airbags, seatbelts, crash-test dummies and seats. During this training, particular emphasis will be put on modelling methods and the practical application of the features.

 

The seminar will describe the fundamentals regarding the composition of an LS-DYNA occupant safety simulation, including the positioning and fitting of seatbelts to the dummy, the definition of recommended contacts between the safety systems, and the design of uniform-pressure airbag models.

Content:

    • Overview of current impact load cases (side, frontal, rear).
    • Barrier models available in LS-DYNA.
    • Dummy models available in LS-DYNA, and their validation methods.
    • Materials, elements and links used for occupant safety simulations.
    • Use and positioning of dummies
      • How to position the dummy in the vehicle?
      • How to prestress the seat foam?
      • How to analyse signals, and which signals to analyse, at a dummy?
      • What are the injury criteria?
    • Definition and fastening of seatbelts.
      • How to model seatbelt, belt deflector/tensioner?
      • How to fit the seatbelt to the dummy?
    • Airbag technology
      • How an airbag system works?
      • Tank test
      • Control volume approach
      • Wang-Nefske formulation
      • Possibilities and limits
      • Syntax and fundamental terms of airbag simulations with LS-DYNA
      • Specific options to define materials
      • Surrogate models for airbag restraints, fire proofing
      • Surrogate models for outlet openings
      • Jetting
      • Composition of an LS-DYNA simulation model

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