Abstract
Friction is a nonlinear phenomenon being present between moving components. For the axis of a machine tool, frictional and control effects have a strong influence on the system's dynamic behavior. Due to their nonlinearity, frictional effects are usually modeled using time consuming transient simulations. This paper presents an approach to efficiently linearize frictional effects for a given excitation based on the nonlinear behavior of the system. The linear friction models can be used together with linear models of the control for an efficient frequency domain analysis of the dynamic behavior, while preserving high accuracy.
