Modeling Drivetrain Systems

SimDriveline provides libraries of one-dimensional mechanical components. You can connect components, such as planetary gears, clutches, and brakes, to model your mechanical system. The models you create can be grouped into subsystems, making them easier to read and reuse.

In addition to the traditional input-output or signal flow connections used in Simulink®, SimDriveline uses physical connections that permit the flow of power in any direction. Models built using physical connections (also referred to as acausal models) closely resemble the physical system they represent, and are easier to understand and share with others.

Many of the component models in SimDriveline let you adjust the level of fidelity. You can choose to include or neglect certain effects, such as meshing and viscous losses, and as a result, balance the tradeoff between model fidelity and simulation speed.
