A free Modelica library for planar mechanical multi-body systems
It is planed to release a new version 2.0.0 by end of November 2025. Pre-release versions will be released in the next time to test the library in advance, so please check releases from time to time when you are interested.
Reference results are prepared for regression testing as well.
We start with v2.0.0-alpha.
The PlanarMechanics library is an open-source Modelica library for the modelling of planar mechanical multi-body systems. Its main components are:
- parts such as mass, rigid rods, fixation
- joints such as prismatic joints or revolute joints
- force elements such as spring and dampers
- sensors and sources
- components for vehicles: wheel models
- components for gearboxes
- many examples
