چکیده
www.mathworks.com Two approaches are available for modeling mechanical friction: continuous and locking. The method you select depends on the system being modeled and on your simulation goals. This article describes methods for modeling and simulating continuous and hybrid continuous-locking mechanical friction using Simulink, Simscape, SimDriveline, and SimMechanics. Topics covered include: • Numerical simulation • Important friction approximations • Trimming and linearization • Real-time simulation

متن کاملDevelopment of a New Dynamic Friction Model for Analytical Modeling of Elliptical Vibration Assisted Turning Process
A new dynamic friction model for modeling of elliptical vibration assisted turning (EVAT) was developed in this research. The periodic change of the friction force direction is known to be one of the most important causes of this phenomenon. In modeling of machining processes (including the EVAT process), static Coulomb friction model was employed by most of the researchers. Because of the peri...
