Description

Simple pulley without mass and inertia. The flange positions s = flange_a.s (right), s1 = flange_b1.s (top left) and s2 = flange_b2.s are constrained by the equation:

    (L + s) = (s1 + s2)/2 .

Parameters

    Pulley_0

  • L [m] : Geometric constraint L=(s1+s2)/2-s (L): Scalar.

Ports

  • Port 1 at left position: implicit input fixedport numbered 1.
  • Port 1 at right position: implicit output fixedport numbered 1.
  • Port 2 at right position: implicit output fixedport numbered 2.
