A Second-Order Dynamic Friction Model Compared to Commercial Stick–Slip Models

Friction has long been an important issue in multibody dynamics. Static friction models apply appropriate regularization techniques to convert the stick inequality and non-smooth stick–slip transition of Coulomb’s approach into a continuous smooth function sliding velocity. However, regularized force is not able maintain long-term stick. That why dynamic were developed recent decades. The depends herein only on velocity but also internal states. probably best-known representative, LuGre model, based fictitious bristle realizes too-simple approximation. recently published second-order model describes dynamics more accurately. It characteristic, which can due shift regularization. Its performance compared here models, launched ago by commercial software packages. results obtained virtual test-bench practical festoon cable system are very promising. Thus, may serve as alternative models.
