Description

Transmission

This models represents any type of lever with ports moving in the same direction. The lever is ideal, i.e., it does not have inertia, friction or geometrical limitations. The lever has one fast moving port and one slow moving port. The transmission ratio is the ratio of the velocities of both ports. The causality of this model is always mixed: one port has a force out causality while the other has an velocity out causality:

 

p_fast.F = i * p_slow.F

p_slow.v = i * p_fast.v

 

or:

 

p_slow.F = 1/i * p_fast.F

p_fast.v = 1/i * p_slow.v

Fast moving rotation port.

Slow moving rotation port.

Parameters

 

i

transmission ratio p_slow.v / p_fast.v [], 0 < i < 1

 

Note

Keep the transmission ratio i between 0 and 1. Confusion might otherwise exist:

i > 1: the fast moving port is slower than the slow moving port (you better interchange the connections of the transmission model).
i < 0: the ports are counter-moving (use the lever model instead).
