BENACCHIO, SimonGIRAUD-AUDINE, ChristopheTHOMAS, OlivierAbstract
This study proposes to investigate the effects of dry friction on the behaviour of a parametrically excited nonlinear oscillator using a pendulum as example. A harmonic balance method and time integration simulations are used to respectively compute and validate the solutions of the problem and their stability. The effects of dry friction on the behaviour of the system are discussed.
