Rigid Body Dynamics problems

RBDyn problems are described as:

  • There are some rigid objects in the space
  • The relation between the objects is known
  • We know the initial condition for each object.
  • We want the values in further times:
    • Kinematic: position, velocity and acceleration
    • Reactions: Force and Moment

An example is a connecting rod of a motor:

biela

So, this library does the simulation and returns the requested values: position, forces and so on.

For more details, please see our Start Guide.

Installation

We use python with the following libraries:

  • numpy: Used for vector calculs
  • sympy: Used to calculate the algebric derivative

This library is available in PyPI. To install it just enter the line

pip install compmec-rbdyn

Or install it manually

git clone https://github.com/compmec/rbdyn
cd rbdyn
pip install -e .

For the tests we use pytest. Type the command in the main folder

pytest
