mechanisms.components

Components: storage (springs), dissipation (dampers), inertance (masses) and sources.

Modules

base

Component base class: something acting on one coordinate, of one of four kinds.

constrained

Constrained elements: springs and dampers that act along one direction n only (a cart).

dissipation

Dissipation components: dampers with f(y, ẏ) and f·ẏ ≤ 0.

gated

A gate on an element: its force times a number between 0 and 1.

inertance

Inertance components: masses and inertias, with kinetic energy ½ ẏᵀ M ẏ.

locomotion

Locomotion components: springs whose stiffness follows the phase of a gait.

sources

Source components: forces whose power is metered in the energy accounting.

storage

Storage components: springs with an energy V(y) ≥ 0 and the force f = −∂V/∂y.
