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

Click For Summary

Discussion Overview

The discussion centers around the analysis of gap values between two contact surfaces, specifically O-rings, using ANSYS software. Participants explore the methods for determining these gap values, the impact of O-ring configuration, and the implications of pressure on the analysis.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant describes their project involving the analysis of gap values between two O-rings and seeks clarification on discrepancies in results obtained through ANSYS.
  • Another participant inquires about the configuration of the O-rings and other components involved in the analysis.
  • A participant provides details about the O-rings being frictionless and subjected to pressure, indicating that the goal is to assess leakage and determine the most effective analysis method.
  • A later post includes a visual representation of the setup, though details of the image are not specified in the text.

Areas of Agreement / Disagreement

Participants have not reached a consensus, and multiple aspects of the analysis remain open for discussion, including the reasons for discrepancies in gap values and the best methods for analysis.

Contextual Notes

Limitations include potential missing assumptions about the O-ring material properties, the specific commands used in ANSYS, and the mathematical steps involved in the gap calculations.

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...
