Can ANSYS Analyze the Difference in Gap Values for Contact Surfaces?

AI Thread Summary
The discussion focuses on analyzing the gap values between two O-rings using ANSYS for an internship project. The intern has used "node to node" contact commands and probed the gap but found discrepancies in the results. The supervisor is seeking clarification on the reasons for these differences. The O-rings are configured to be frictionless with pressure applied, affecting their deformation and the resultant gap. The goal is to assess leakage through the O-rings and identify the most accurate analysis method.

I'm an intern currently and doing some analytic project in a company. So i am required to determine the gap between 2 contact surface (2 O-rings). I've obtain some result by using "node to node" contact with some commands and also probe "gap". There's some difference between the results and the supervisor want me to find out why is there difference between the gap value. Is there anyway i can find it out? Anyone here know the reason behind the calculations/analysis behind ansys. And is it possible to determine the gap by the deformations of the 2 O-rings. Thanks.

What is the configuration of the O rings and other components ?
 
the O rings were frictionless to each other and there are pressure acting on them so that both O-rings will press against each other... the end effect is to determine that the leakage through them with Gap and find out which is the better analysis
 
it look this way...

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
