Abstract


The lubricating film nanoscale testing technology is the study of nanoscale lubrication film features one of the key issues, with precise lubrication film thickness measurement can film lubrication deeper, in order to better address the actual working conditions of lubrication problems. With the in-depth study of the theoretical and practical application of the thin film lubrication film lubrication film thickness measurement technology and equipment put forward higher requirements. Especially the rapid development of industrial control technology and computer application technology, the rapid development of computer-based control technology, control the process and the rule is more complex and sophisticated, the control method is also more flexible, to nanoscale lubrication film measurement instrument intelligent integration provides an unprecedented opportunity. This thesis were the following: (1) analysis of the situation and development trend of domestic and foreign film lubrication, has an important role and significance of the measurement method for the study of thin film lubrication. NGY nanoscale lubrication film measuring instrument inadequacies, design new nanoscale lubrication film measurement instrument application software system. (2) describes the measurement method and the principle of the lubricating film at home and abroad has been widely applied, and details NGY-6 type nanoscale film thickness of the lubricant film measuring instrument measuring principle of optical interference principle of relative intensity. (3) analysis of nanoscale lubrication film gauge the overall structure, hardware systems, etc., for the development of nanoscale lubrication film measurement instrument's hardware system's characteristics and the practical application of the need, the appropriate application software carry out the overall design, including software the choice of platform and development tools, software modules, workflow software framework design and software to achieve. (4) Intro of nanoscale thickness measurement system software system design, based on the features of the software to achieve human-machine interactive display interface, software, image acquisition, data analysis and processing, parameter adjustment control, document management program design and implementation, that is, to achieve the the interference image display, data acquisition and processing, film thickness measurement, friction measurement, curve drawing, storage and monitoring of the process of integration. An example to verify the actual effectiveness of the development of software systems, and laid the foundation for the further study of thin film lubrication theory. Finally, the summary of the main conclusions of the thesis work worthy of in-depth study of the work, and follow-up are discussed.
