However, they are unable to maintain static friction in detail. For this reason, dynamic friction models have been developed and published in the literature. However, commercial multibody simulation packages such as Adams, RecurDyn, and Simpack have developed their own specific stick-slip models instead of adopting one of the public domain approaches. This article introduces the fundamentals of these commercial models and their behavior from a practical point of view. The stick-slip models were applied to a simple test model and a more sophisticated model of a festoon cable system using their standard parameters.}, language = {en} } @misc{SchudererRillSchulzetal., author = {Schuderer, Matthias and Rill, Georg and Schulz, Carsten and Schaeffer, Thomas}, title = {Dynamic Stick-Slip Models based on Continuous and Discontinuous Friction Characteristics}, series = {ENOC - European Nonlinear Dynamics Conference, 11th, 2024, Delft}, journal = {ENOC - European Nonlinear Dynamics Conference, 11th, 2024, Delft}, doi = {10.2139/ssrn.5014569}, pages = {17}, abstract = {This paper presents the implementation of a recently developed continuous second-order dynamic friction model (FrD2) in the commercial multibody system software Simpack, where it is evaluated against Simpack's discontinuous friction model for stick-slip applications in terms of performance. A method for adapting parameters from the well-known LuGre model to the FrD2 model is introduced. The FrD2 model accurately captures complex friction phenomena, including the Stribeck effect, which is essential for simulating friction-induced vibrations. Tested on a festoon cable system and a belt model, the FrD2 model demonstrates itself as a robust alternative to both the LuGre and Simpack models, especially for applications requiring continuous transitions between static and dynamic friction states, long-term stiction effects, and other complex friction behaviors.}, language = {en} }
