How do I make a Double-Acting Hydraulic Cylinder act in both directions in Simscape?

Hi All,

I found that one of the parameters for the cylinder restricts it to move in one direction only (positve/ negative).

Is there anyway to allow both directions? For example if my pump speed is given in the form of a sine wave, how do I get the cylinder to act in both direction depending on the pump speed?

from help:

Initial Conditions Tab

Piston initial distance from cap A

The distance that the piston is extended at the beginning of simulation. You can set the piston position to any point within its stroke. The default value is 0, which corresponds to the fully retracted position.

Hey Alex,

I tried playing around with the initial conditions but it'd throw an error when it got fully extended and it would not return to its initial position or anything. The cylinder would still only act in one direction.

It is difficult to understand something without a model, if you are sure that things are in the cylinder, open the help on it and study examples of models. Perhaps you are setting the movement or calibers incorrectly ...
