Classic examples are squealing brakes, stiction in robotic arms, or stick-slip in linear drives. To properly design and understand mechatronic systems of this type, good quantitative models of transient friction effects are of primary interest. The theory developed in this book approaches this problem bottom-up, by deriving the behavior of macroscopic friction surfaces from the microscopic surface physics. The model is based on two assumptions: First, rough surfaces are inherently fractal, exhibiting roughness on a wide range of scales. Second, transient friction effects are caused by creep enlargement of the real area of contact between two bodies. This work demonstrates the results of extensive Finite Element analyses of the creep behavior of surface asperities, and proposes a generalized multi-scale area iteration for calculating the time-dependent real contact between two bodies. The toolset is then demonstrated both for the reproduction of a variety of experimental results on transient friction as well as for system simulations of two example systems. | | 出版日期 | Book 2013 | | 关键词 | Creep Behavior of Surface Asperities; Rough Surfaces; transient friction | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-7091-1506-0 | | isbn_softcover | 978-3-7091-1686-9 | | isbn_ebook | 978-3-7091-1506-0Series ISSN 1612-1317 Series E-ISSN 1868-1212 | | issn_series | 1612-1317 | | copyright | Springer-Verlag Wien 2013 |
