Simulations of simple and double pendulums

Primary LanguagePython

Pendulum Simulations

This is a mini project that produces simulations of simple or double pendulums with Python. It produces animations of custom systems with one or more classical pendulums and includes graphs of angular displacements and phase space (for double pendulums only).

Requirements:

  • matplotlib
  • numpy

Instructions

To simulate a simple pendulum system:

test_pendulum = Pendulum(length=1.0, mass=2.0, theta=120, omega=0) 
test_system = system([test_pendulum]) # initialize a list of pendulum objects in a system
animate_pendulum(test_system) # animate the system

Double Pendulum with phase portrait:

pendulum1 = Pendulum(1.0,2.0,70,0)
pendulum2 = Pendulum(1.0,2.0,120,0)
pendulums = [Double_Pendulum(pendulum1,pendulum2)]
test_system = system(pendulums)
animate_pend_graph(test_system, graph='phase space')

10 double pendulums with 0.1 difference in angular displacement:

pendulum1 = Pendulum(1.0,2.0,70,0)
pendulums = [Double_Pendulum(pendulum1, Pendulum(1.0, 2.0 + 0.1*i, 120, 0)) for i in range(10)]
test_system = system(pendulums)
animate_pendulum(test_system)
