Double Pendulum

This code implements equations of motion for a coupled system of pendulums.

See this derivation and explanation for more details.

To run

Make sure you have python3 installed.

git clone https://github.com/jalexvig/double_pendulum
cd double_pendulum

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

python main.py 

To change the parameters of the system (e.g. pendulum masses/lengths), open main.py and modify the dictionary system_params:

system_params = {
    'm_1': 1,
    'l_1': 1,
    'm_2': 1,
    'l_2': 1,
    'g': 9.81
}
