15 صفحه اولOn Self-excited Vibrations Due to Sliding Friction in Systems of Deformable Bodies – General Formulation and Influence of Contact Properties –
This contribution presents a generalized approach to friction induced vibrations in systems of moving continua. To this end, Hamilton’s Principle is used to state a weak formulation of the system dynamics without using specific structural models, like beams or plates for instance. The normal contact is enforced by a penalty formulation, which motivates the use of a constitutive contact model ba...
متن کاملFriction Force for Self-Excited Systems
Control and reduction of friction is one of the last frontier in the field of tribology. This paper presents a model for low friction made up of a self-excited oscillator sliding along a periodic potential. Many examples of such self-excited oscillators in electrical, mechanical and biological systems can be found in literature. As one of its most prominent features, stable limit cycles in phas...

متن کاملForced large amplitude periodic vibrations of non-linear Mathieu resonators for microgyroscope applications
This paper describes a comprehensive nonlinear multiphysics model based on the Euler-Bernoulli beam equation that remains valid up to large displacements in the case of electrostatically actuated Mathieu resonators. This purely analytical model takes into account the fringing field effects and is used to track the periodic motions of the sensing parts in resonant microgyroscopes. Several parame...
