PTDynamics Library

PTDynamics includes models for shafts, bearings, gear meshes, flexible joints and complex assemblies such as epicyclic and differential models, along with the associated mounting systems. It has been developed for modelling automotive transmissions and drivelines but can be applied to any powertrain system.

One of the key application areas for the PTDynamics Library is to model driveability. Using the Library we can capture the full motion of the powertrain systems on their mounting systems to understand the vehicle response.


Chassis models are included within the Library that are suitable for straight line tests. The chassis models include Pacejka tyre slip and simple suspension so that the vehicle can pitch and bounce under acceleration. To capture more complex interactions with the suspension then the Vehicle Dynamics Library can be used along with this Library.
