Domains: Continuous. Size: 1-D. Kind: Iconic Diagrams (Translation).
This models represents a crank and rod mechanism. The mechanism is ideal, i.e., it does not have inertia, friction or geometrical limitations. It has one rotation port (p_in) and one translation port (p_out). The causality of this model is always mixed: one port has a force out causality while the other has a velocity out causality:
p_in.T = i * p_out.F
p_out.v = i * p_in.omega
The transmission ratio (i) is the ratio of the velocities of both ports. It is a function of the shaft angle, the crank length and the rod length.
