Nonlinear dynamics of a flexible mechanism with impact

Journal of Sound and Vibration, 2006
The nonlinear dynamics of a slider-crank mechanism with a flexible rod is considered in this study. The flexible rod is modeled with lumped masses and periodically impacted by an external flexible sphere. The impact is modeled using a kinematic coefficient of restitution.

Dynamical Integrity of Nonlinear Mechanical Oscillators

2008
This work overviews and continues recent investigations of the authors [1, 2] on the dynamical integrity of nonlinear mechanical systems and other oscillators. In fact, it has been realized that attractors must be paralleled by uncorrupted basins for safe practical applications [2, 3].

Nonlinear dynamics of a two-body nonlinear mechanical system

Computer Methods in Applied Mechanics and Engineering, 1991
Abstract Based on the example of a sixth-order set of nonlinear differential equations governing the dynamics of a mechanical system with three degrees of freedom, this paper presents a numerical method for the systematic tracing of structural changes of the phase flow, which accompanies changes in the chosen system parameters.

Nonlinear Dynamics of an Electro-Mechanical Energy Scavenger

This paper presents a very compact electro-mechanical wideband energy harvester optimized for tire applications. The energy conversion process of the device takes into account the simulation of different phenomena like: non linear dynamic and adaptive resonant behavior of the seismic mass, electromagnetic and magneto-static coupling between floating ...

Dynamic models of mechanisms with nonlinear characteristics

Soviet Applied Mechanics, 1983
The general equations of four representative dynamic models are presented. The nonlinearities are caused by: reactions of elastic elements, kinematic transmission function depending on the position, nonlinear kinematic transfer function, and variable transmission realizing elastic slipping.

Nonlinear Dynamic Phenomena in Mechanics

2011
Nonlinear phenomena should play a crucial role in the design and control of engineering systems and structures as they can drastically change the prevailing dynamical responses. This book covers theoretical and applications-based problems of nonlinear dynamics concerned with both discrete and continuous systems of interest in civil and mechanical ...

Mechanism and nonlinear dynamics of an oscillating chemical reaction

Journal of Statistical Physics, 1987
A mechanism and a model of a ferroin-catalyzed oscillating chemical system are descrined. This reaction presents an excellent example of a far-from-equilibrium system that forms spatial and temporal dissipative structures. The model shows that while the well-stirred system has a unique and stable stationary state, the same reagent spread in a thin ...

Nonlinear Dynamical Systems in Mechanics and Biology.

1995
Abstract : This grant was in its final no-cost extension during academic year 1994-5. Following the PIi's move to Princeton University, te remaining funds on the grant were administered under Cornell,/Princeton Subcontract 20188-5423. They were to partially support the PI, Philip Holmes, during the academic year and summer 1995, and to support visiting
