Vehicle Dynamics Library provides an open and user-extensible environment for full vehicle and vehicle subsystem analysis. Designed with a hierarchical structure and an extensive library of predefined vehicle components, the configuration of any class of wheeled vehicle – cars, trucks, motorsport vehicles, heavy vehicles – is convenient and straight-forward.
The library allows you to optimize and verify the design of your vehicle systems from the early design phases through control design and implementation. It is unique in that it provides true multi-body, multi-domain simulation with real-time performance, and model export capabilities allowing distribution across your organization.
In the left model, the engine and transmission are used in a full vehicle, connected via the driveline to the wheels and the chassis.
In the right model, the context is switched to focus on the engine and the transmission. They are connected to a load, which then can be very simplified, e.g. just a 1D mass, or also a full chassis with driveline.
The plots show sample results from the launch simulation and subsequent shift events.
Note the acceleration disturbances around each shift event.
