Dynamic Modelling

The Monash Institute of Railway Technology has long standing experience in dynamic modelling and simulation of railway vehicles. An advanced level of investigation and analysis of dynamic performance of rollingstock and components is performed utilizing extensive dynamic modelling expertise in conjunction with data from the highly reliable instrumented revenue vehicle (IRV) platforms.

Key areas of expertise are:

• Wheel-rail contact modelling
• Assessment of damage (wear and rolling contact fatigue) in wheel-rail contact
• Dynamic wagon and component testing
• Dynamic structural modelling
• Longitudinal train dynamics and driving strategies
• Vehicle performance assessment including stability and ride quality
• Service life assessment and analysis
• Vehicle-track interaction
• Vehicle component assessment and optimisation including brakes, couplers, and suspension
• Derailment investigation, cause identification and risk mitigation
• Interaction with trackside components, such as tunnels, cuttings, bridges and unloading indexers
