Rolling stock test and fatigue design criteria

Objectives

• Research into innovative structural concepts
• Propose efficient, economically viable solutions for fulfilling a particular function
• Establish, analyse and confirm mechanical dimensions
• Provide proof for rolling stock type approval
• Identify the causes of component failures

Test
facilities

EXTRAS

• Design optimisation = weight advantage
• Type approval of a structure with fewer physical tests
• Shorter timelines for developing a new concept
• Approval of a component to be used under new operating conditions (weight, for example)

INPUT DATA

• Rolling stock characteristics
• Digital model of bogie frame and body (CAD)
• Bogie/frame component diagrams
• Laws of behaviour of materials
