Dymola Powertrain Library
The Powertrain library contains components to enable the simulation of the whole powertrain system including the resulting motion of the vehicle. This enables the prediction of attributes such as vehicle performance, fuel economy and driveability, which in turn can aid the development of the powertrain control systems and components.
Extensive range of components
The Powertrain library includes engine, transmission, driveline and vehicle models for a wide range of applications. Map based internal combustion engine models are available along with manual and automatic transmissions that can all be coupled to front, rear or four wheel drive driveline models.
The level of detail in each of these components can be easily varied to suit different applications. Rigid elements are available for fuel-economy studies and compliant variants exist to enable the simulation of driveability. Handling of speed and torque dependent friction a unique feature of the Powertrain library is efficient and robust handling of speed and torque dependent friction based on sound research results. Therefore, gear efficiency is easy to simulate. Many elements in the library include speed and torque dependent losses as an option.
Considers 1D and multi-body motion
The library consists primarily of 1D rotational components for modelling the motion of the powertrain. All of the models can also be used to model the reactions into the powertrain mounting system and consider the 3D effects on a multi-body system. Compatible with the VehicleInterfaces library The VehicleInterfaces library defines an architecture for modelling the entire vehicle system. Compatibility with this library means that models built using the Powertrain library can be easily coupled to models from other automotive Modelica libraries such as the Transmission, VehicleDynamics and SmartElectricDrives libraries.
