Title: | On the oscillation death phenomenon in a double pendulum system with autoparametric interaction | Authors: | Kovačić, Ivana Zuković, Miodrag Cartmell M. |
Issue Date: | 1-Jan-2012 | Journal: | Journal of Physics: Conference Series | Abstract: | This study is concerned with autoparametric interaction in a four degree of freedom damped mechanical system consisting of two identical pendula fitted onto a horizontal massive rod which can oscillate vertically and rotationally. One pendulum is harmonically excited. The equations of motion indicate that autoparametric interaction is possible by means of typical external and internal resonance conditions involving the system natural frequencies and excitation frequency. An intriguing phenomenon is demonstrated when the unforced pendulum is decoupled and no energy goes into it, as a result of which it stops oscillating. Numerical simulations are carried out to determine when and why this phenomenon occurs for a different excitation magnitude as well as for zero and non-zero initial conditions of the unforced pendulum. © Published under licence by IOP Publishing Ltd. | URI: | https://open.uns.ac.rs/handle/123456789/13219 | ISSN: | 17426588 | DOI: | 10.1088/1742-6596/382/1/012055 |
