Research and development

VÚKV a.s. performs a wide spectrum of calculations designed to verify if the proposed solutions meet the requirements. 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 requirements;
    • Optimisation of constructions and failure analyses;
    • Assessment of constructions for fatigue of material and operation strength pursuant to valid standards;
    • Linear analyses (FEA, permanent strength assessment);
    • Non-linear analyses (FEA – material and geometric non-linearity, contact tasks);
  • Crashworthiness calculations;
  • Simulations of railway vehicle running behaviour:
    • Running safety;
    • Impact on the rail;
    • Stability;
    • Riding comfort;
    • Safety and protection against derailment on twisted track;
    • Sway coefficient;
    • Cross wind effects;
    • Flexible body calculations;
  • Running gear design and optimizing:
    • Suspension calculations;
    • Shock absorption calculations;
  • Design and optimisation of traction systems;
  • Rolling stock construction gauge calculations;
  • Design and optimisation of braking systems:
    • Braking calculations pursuant to UIC;
  • Thermic calculations:
    • Ventilation;
    • Heating;
    • Air conditioning.
