Analysis of Friction Induced Mode Coupling Instability

Mode coupling instability mitigation in friction systems by means of nonlinear energy sinks: Numerical highlighting and local stability analysis

In this paper, we study a problem of passive control of friction-induced vibrations due to mode coupling instability in breaking systems. To achieve that, the well-known two degrees of freedom Hultèn’s model, which reproduces the typical dynamic behavior of friction systems, is coupled to two ungrounded Nonlinear Energy Sinks (NES). The NES involves an essential cubic restoring force and a line...

Saturation of the Farley-Buneman instability via three-mode coupling

[1] Characteristics of type-1 radar echoes obtained from the E region ionosphere have yet to be conclusively explained. The dynamical properties of the saturated state of the FarleyBuneman instability are widely thought responsible for these type-1 echoes. In this paper we present a different perspective and new details on a previously proposed three-wave coupling mechanism (Otani and Oppenheim...

Non-linear Mode Coupling and Saw-Tooth Instability

Dynamics of the longitudinal relaxation oscillations of a single bunch above the threshold of microwave instability is discussed.
