Calculations - Support

Calculations form an integral part of research and development. Their purpose is to confirm that the proposed construction design will meet the required parameters or to suggest where there is a need for change for achievement of compliance with the required parameters.

The company performs a large number of different calculations as part of the development process. The calculations can be classified as follows:

• Strength calculations:
  
  
  • Complex calculations of railway vehicles and their components based
    on European standards, UIC decrees and customer requierements,
  • Optimisation of constructions and failure analyses,
  • Assessment of constructions for fatigue of material and operation strength pursuant to valid standards,
  • Linear calculations (FEM, assessment of permanent strength),
  • Non-linear calculations (FEM - material and geometric non-linearity, contact tasks),
  • Crash calculations.
• Simulations of riding properties of railway vehicles:
  
  
  • Traffic safety,
  • Impact on the rail,
  • Stability,
  • Comfort, vibrations,
  • Safety and protection against derailement on a twisted track rail.
• Running gear design and optimisation:
  
  
  • Suspension calculations,
  • Shock absorption calculations.
    
    
• Rolling stock construction gauge calculations.
• Design and optimisation of traction systems.
• Design and optimisation of braking systems:
  • Braking calculations pursuant to UIC.
    
    
• Thermal calculations:
  • Ventilation,
  • Heating,
  • Air conditioning.
