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
