Transient friction effects determine the behavior of a wide class of mechatronic systems. 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...

Approaching transient friction effects by deriving the behavior of macroscopic friction surfaces from microscopic surface physics, this book proposes and demonstrates a multi-scale iteration for calculating the time-dependent real contact between two bodies.
