dynamic application piston

[Filo]

I just can't... How do I simulate an oleodynamic piston within the "dynamic simulation" module?
It would be enough for me to do something similar to the "cylinder" joint, where instead of having as input the force had the race.

Hi.
Thank you.

Hi.
Thank you.

I'd say the cylindrical joint is fine. what you can do is play on design variables.
you can impose a constant execution speed at the jack (or a function) and obtain the necessary force for the operation at regimen (pump size), impose initial position conditions or contact constraints, or still control the position at the moment (dof t joint cylinder edict position position and by chart decide its position during the time line).

if the pencil is not an actuator but a dampener are interesting the dampers and jacks found in the spring/damper/jack joint

as usual I explained badly.. .

I managed to insert the cylinder as a dampener, I imagine jack in English, and I can't insert it instead as an actuator, and so I don't have the card to which you refer where I can choose the motorcycle laws.

In practice I have to study the behavior of a parallelogram that is moved by a hydraulic jack placed on the diagonal.

Thank you very much

so if it is actuator you cannot use spring/jack/damper joint

the cylindrical bond is fine.

After creating that bond, doubleclick it from the browser, you will have a window where you can manage the degrees of freedom (dof) related to it.

for each dof there is an edit rank position, and for that voice you can choose to control speed, position, etc.


for each of these choices you can choose a constant value or use a law (graphic from the drop-down menu), where for each coordinate choose the relative position value (or speed)

In the first example, I set a constant speed of 2 mm/s

In the second case, package compression, I imposed a position law based on time.

the joint used was only the cylindrical.

...
after the creation of this bond. . .
...

here is the problem, in fact, and I understood this after reading more carefully the online guide, under the cove "standard joints" I only "space", I miss "cilindrical" "prismatic" "revolution" etc.

Hi.
Thank you.

ps I also wanted to attach the axieme but I can't make the pack'n go

I didn't see the last 2 videos you posted, now I'm checking them out.
