I simulate seal ring contact max pressure by workbench,fluid pressure was applied during the simulation,then I check the maximum contact pressure.I find there are two ways,but I can't confirm which way is right.These two way result like below.If I want use the second way(the last pic),what need I do ? thank you.

Hey,

These are different representations of the pressure contours.

You may refer to this material Applications of Contact | Ansys Innovation Courses; Analysis of an O-ring Seal — Lesson 3 | ANSYS Innovation Courses on o-ring.

Thanks,

Deepak

I have see this video,but I can't find how to set about maximum contact pressure,can you tell me how use pressure contours to show the maximum contact pressure(like last picture).Thank you.

[Deepak]

Can u please share the source of the second plot?

[Chen Yi]

The second plot from one paper,there are many picture like this to show maximum contact pressure.I'm not sure this display is correct.Can you help me to confirm. Thank you.

Hi Deepak:

Can you help me to confirm and how to set to show like the second plot?

Thank you.

[Deepak]

Hi,

I was not allowed to access the links. But I think they used another external extension to plot as a vector.

Max pressure can also be indicated in 1st plot.

Thanks,

Deepak

Hello Deepak:

         Do you know how to  display vector plot  when I use  workbench simulate o-ring maximum contact pressure? Or can I only rely on external extension ?

thank you.

[Deepak]

We do not have any for that as far as I know I am afraid.

Hi Deepak:

       OK ,Thank you.In other words,how it is used to evaluate sealing performance?Whether to look the maximum contact pressure like the first picture? Now I want to confirm if I use the first picture,is it right ? Thank you.

The probe can be used to identify the location of max. pressure
