Modeling and analysis of rigid multibody systems with translational clearance joints based on the nonsmooth dynamics approach. (English) Zbl 1219.70014
Arczewski, Krzysztof (ed.) et al., Multibody dynamics. Computational methods and applications. Selected papers based on the presentations at the ECCOMAS conference on multibody dynamics, Warsaw, Poland, June 29–July 2, 2009. New York, NY: Springer (ISBN 978-90-481-9970-9/hbk; 978-90-481-9971-6/ebook). Computational Methods in Applied Sciences 23, 107-130 (2011).
The authors address the title problem in considerable detail. Compared with revolute and/or spherical joints, translational joints pose greater modeling difficulties due to the variety of possible contacts between the slider and the channel (e.g. no-contact, single-point contact, double-point contact, contact at leading or following points).
The authors model the slider/channel contacts as multiple unidirectional friction and impulse forces with normal and tangential components. Coulomb friction is used to model the sliding forces.
Although the phenomena are extremely complex the authors are able to present a clear exposition which should be of interest and use to both researchers and designers. As an aid the paper presents an illustrative example using the classical slider-crank mechanism.
