Heavy rail / Urban light rail

Rolling stock test and fatigue design criteria

Optimising the dimensions of vehicle bodies and bogies frames

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

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
