Numerical Simulation of Railway Accidents for Passive Safety Analysis (SSP)

Lecturer

Marta Carvalho

Objectives

• Fundamental concepts about numerical simulation applied to the study of passive passenger safety.
• Potentials and limitations of the use of commercial codes, encouraging their rational and appropriate use with regard to the representation of real systems and their components.

Requirements on previous knowledge

None.

Program

• Presentation and definition of concepts and objectives using LS-Dyna; Typical train interior configurations.
• Workshop: introduction to LS-PrePost (2 classes of basic examples in which pre- and post-processing of models in LS-Dyna is carried out).
• Impact biomechanics (2 classes): injury mechanisms, injury criteria, standards and regulations. Anthropomorphic testing devices; Applications in LS-DYNA.
