| Summary: | 碩士 === 元智大學 === 機械工程學系 === 90 === In the forming processes of metal, liquid lubricants are still used in industry extensively . With the products being more and more complex, it may apply two different qualities of lubricants to a processing process. However, it will cause double friction interface problem. Therefore , it is unreasonable that if we take the whole processing interface to be a single friction interface. We have to rely on numerical operation , experiment and computer simulation to estimate the friction coefficient of the whole processing interface.
The main purpose of this research is to obtain the individual friction coefficient of the double friction interface. The model combines a rigid-plasticity finite element code with realistic friction model to simulate the extrusion processes in the part of theoretical simulation . With the respect to the experiment , we use different qualities of lubricants to make double friction interface. The friction coefficient of the double friction interface can be evaluated from the combination of theory and experiment .
