Bicycle Parameters Module

A python program designed to produce and manipulate the basic parameters needed for the Whipple bicycle model.

https://travis-ci.org/moorepants/BicycleParameters.svg?branch=master

Dependencies

Required

Optional

These are required to build the documentation:

Installation

The easiest method to download and install is with pip:

$ pip install BicycleParameters

There are other options for getting the source code:

  1. Clone the source code with Git: git clone git://github.com/moorepants/BicycleParameters.git
  2. Download the source from Github.
  3. Download the source from pypi.

Once you have the source code navigate to the directory and run:

>>> python setup.py install

This will install the software into your system and you should be able to import it with:

>>> import bicycleparameters

Example Code

>>> import bicycleparameters as bp
>>> import numpy as np
>>> rigid = bp.Bicycle('Rigid')
>>> par = rigid.parameters['Benchmark']
>>> rigid.plot_bicycle_geometry()
>>> speeds = np.linspace(0., 10., num=100)
>>> rigid.plot_eigenvalues_vs_speed(speeds)

Sample Data

Some sample data is included in the repository but a full source with all the raw data files can be downloaded from here:
