SIMPACK

Simpack Rail allows the modeling and analysis of any kind of rail-guided systems. The most common applications include High Speed, Intercity, local Trains, Locomotives, Trams, Freight Cars as well as Special Vehicle, like Roller Coaster and Suspended Rails.

The standard vehicle components are available, like wheelsets, independent wheels and profiles as well as a large library of suspension elements, e.g. shear springs, damper, friction elements, bearings and air spring systems.

Arbitrary track layouts of arbitrary complexity are easily entered with inertia-fixed and elastic track components, including additional track irregularities. Track feature as turnouts, crossing, switches are as common applications as infrastructure modelling of canternary and overheadline structures in contact with the pantograph.

Different wheel-rail contact methods are available with a different degree of complexity and insights in to the normal and shear stress distributions of the slip and stick regions within each contact patch.

Flexible track sections can be introduced into the track line design to simulate the dynamics forces on bridges, turnout and crossings.

Rail Wear allows users to predict the wear (material removal) of railway wheels and/or rails. The amount of material removed from the wheel or rail after the simulated run is estimated by using the contact patch positions/sizes and contact forces/creepages.

Users can choose between the 'Krause/Poll' and the more detailed 'Archard' wear laws. Users can also specify scenarios and extend the module with user-specific wear laws.
