PyDy
PyDy provides Python tools for modeling the dynamics of multibody mechanical systems.
About PyDy
PyDy is a workflow and a set of Python software packages for studying multibody dynamics, the motion of connected mechanical bodies. Its core is the SymPy mechanics package, which generates symbolic equations of motion for complex multibody systems. PyDy extends that symbolic output into the numerical domain for simulation, analysis, and visualization. It is built on widely used scientific Python libraries, including NumPy, SciPy, IPython, matplotlib, Cython, and Theano.
The homepage links to download options, documentation, a beginner's tutorial, and two worked examples, a chaotic pendulum and a double pendulum. The most recent dated post in the homepage text is from January 2016, so the project's current status is not clear from this page alone.
