Hello everybody. 

 

I want to make a pneumatic cylinder simulation.i have created a Pneumatic Cylinder and valve but i got this error:

Hello alicanaydogan,

 

there are a couple values I would change. One of the most important values is the "Nominal Flow" (the value should be much less).

I will add an example (MCD NX12.0.2) and here are some screenshots that can be used as reference:

Thank you so much Viktor , it's very helpful to me. But i want to ask you something too Smiley Happy

 

First ; referring this aswer: https://community.plm.automation.siemens.com/t5/NX-Design-Forum/NX12-MCD-pneumatic-pist/td-p/461886

 

shouldn't total amount of Volume extension A and B be equal max stroke ? 

 

Second; i'm triying to learn pneumatic and MCD. How can i improve this? Can you reccomend me any book or manuel ?

In some topics NX Help doesn't explain clearly.

Hi,

 

Thanks for the info. My query is why you are using 4-way Pneumatic valve with single rod cylinder as 3-way is for single rod cylinder and 4-way is for double rod cylinder.

https://docs.plm.automation.siemens.com/tdoc/nx/12/nx_help/#uid:index_mechatronics:xid896275:xid8992...

The other question is what should be the values for 3 way Pneumatic Valve? Can you also please share any formula or something for calculating these numbers? Your reply will be very much appreciated.

 

Thank you
