"The level of user support for VAMPIRE is always excellent and the help we have had over the last week has ensured we can keep our current project moving along at a good pace."

Vehicle Manufacturers

This is the more traditional market for dynamics analysis where simulation can be used at various stages in the design process to develop, evaluate and refine vehicle designs:

  • concept development – simulation enables the user to construct various prototypes and evaluate their performance over a range of operating conditions, helping get designs right from the outset
  • detailed design – dynamics modelling can be used to select components that ensure the design will meet both performance standards and regulatory requirements
  • design evolution – the effect of changes to the design on dynamic performance can be quickly and easily evaluated
  • risk analysis – various “what if” scenarios can be played out in a simulation to evaluate the effect of suspension component failures for example
  • compliance – models can be validated against operational vehicles and used to demonstrate compliance with standards without the need for extensive track testing

Simulations can also be useful to tackle vehicle dynamics problems encountered “in-service” or where vehicles need to be modified or refurbished.

Particular markets also have specific applications. For example, the ability of locomotives to steer effectively minimises wheel wear whilst maximising the amount of effort available for traction and braking. Modelling curving performance can extend both track life and wheel life while ensuring that maximum tractive effort is achieved.
