Modern methods to retrieve innovative material solutions for tribosystems
A numerical, tribological data collection system with 12,100 data records was developed to find materials for tribological operations. The databse enables the user to search, retrieve and display information and data about the appropriate material couples in a fast and conventient way. The database is intended to be used by researchers, engineers, consultants and developers. All tribological characteristics of the listed materials are directly comparable; the data has been compiled and put into a standardized form, which covers the specific properties of nearly all tribometers used. The structure and the precisely defined formats may help guide future scientists and engineers to organize, archive and publish their tribological tests and results in a complete and comprehensive way.
Implementation of commercially available software in the testing, data analysis and databasing phases of tribological research
Thrust washer wear test are routinely performed for material screening and production problem resolution. Significant improvements in both the integrily and efficiency of testing, data analysis and databasing activities resulted from a computerized automation system. This system is the integration of multiple commercialy available personal computer software products : analog to digital conversion/control, spreadsheet, and relational database. The availability of a common macro programming language supporting interproces communication is the primary requirement. Friction coefficient and wear scar geometry analyses are performed using spread sheet macros. On completion of the analysis, the system automatically updates the database and archives raw data. Data integrily is ensured through single entry and paperless operation. Minimal intrusions into the commercial tribometer and profilometer are required, facilitating portability of the system concept. The concept, design, operation and efficiency of this system are presented in block diagram form.
