Contamination of bearing interfaces and sliding contacts in mechanical tribosystems
Contamination of sliding contacts and bearing interfaces can cause machine elements to undergo catastrophic failure. Oftentimes, the failure is due to particulate or wear debris contamination when interfaces are not designed to be robust against contamination. The PFTL employs experiments and/or modeling studies to understand systems that undergo particle contamination. The particle & fluid-structure interaction computational simulation below shows a bearing surface deformed by a transient fluid pressure along with its performance under particle contamination.
